The common vampire bat.

Desmodus rotundus.

The vampire bat live nowhere else but the New Worlds; Mexico, Central America and South America. The vampire bat has a dark, mysterious history, especially when they were introduced by the American natives to European explorers and religious groups. The very idea of a creature that only appears during the darkest of nights to feast on blood struck fear into the hearts of the Europeans. They saw them as tiny minions of the devil. Even though the vampire bats were worshipped as gods by the American natives, the stories created by some native cultures made them horrifying!

In Mexico, there is a Mayan bat god named Tzinacan, the Life Bat. The bat god, Tzinacan, protects the souls and life of the people. It could be simply described as the "angel of death", the Mayan grim reaper. It uses his sharp fangs to cut the silver cord of life that connects the soul to the body. On its great red wings it guides the souls to be judged and sent to their appropriate eternal destination.

Tzinacan has a darker cousin, Camazotz, the Death Bat. This bat was the messenger of death sent by the gods to punish the people when they disobeyed them. Camazotz and its followers of the House of Bats had a very bloody history and reveled in death and blood.

Having such a terrible reputation, very little people sought to understand these mysterious creatures. But, there were one or two people whose love for study and animals has made them curious to understand these tiny animals of the night.

One animal behaviorist was an Italian during the Age of Enlightenment of the 18th century. This animal behaviorist enjoyed studying creatures that were unusual and were unknown. He went to the Americas when he heard the stories from explorers that had visited the lower New Worlds. Stories of waking up from a restful sleep, only to notice in horror that their feet or some extremity of their person covered in blood! The Italian was delighted and thanks to his family's wealthy background and connections was able to join an expedition to the New World.

He settled in a colony in Mexico in the valley of Toluca. He chose this colony for despite the heavy Catholic presence, the people; the Tzoctziles (meaning "people of the bat) still had strong connections to their ancient culture and still quietly worshipped Tzinacan, the Life Bat. He bonded with these people and expressed his fascination of the vampire bats. The people were happy to share their knowledge with one that appreciated their way. The Tzoctziles showned him where the bats roosted and the Italian began his studies. He studied the bats of Toluca for many, many months. As his study expedition was coming to an end, he received a most surprising gift. By accident, a vampire bat was caught and kept. On the day of his departure, he was gifted the bat, a young juvenile bat kept in a basket that was lined with a heavy cloth to keep the light out. The Italian was moved greatly and accepted the gift happily.

He named the bat, Meravigilabuio meaning "dark wonder".

He and Meravigilabuio (Buio, for short) returned to Italy. The Italian's friends and peers were rather disturbed of little Buio. Buio's owner bought chickens and drained them of their blood, even took the time to warm the chicken blood for he learned that he got little response from Buio if he fed him cold blood. Some of the Italian's friends believed that he was serving Buio as if he was a servant to the little bat. But the Italian laughed and joked that there are women that are slaves to their little dogs and fussy cats. The Italian studied Buio and was asked by local artists to bring Buio to drawing and painting sessions. Buio was taken everywhere, of course during the night, inside a birdcage. During the day his cage was draped by a dark sheet to keep the light out.

Buio was young when he was caught. He was very aggressive at being handled by a strange human but overtime he learned quickly that he was getting an easy meal. He was spoiled and would shriek as soon as the air became cool with the night for blood. He was given good exercise, for the Italian would shut up his home tightly, blocked every hole and even had a door installed over the fireplace so Buio wouldn't escape into the night. It was quite fascinating seeing Buio fly about the Italian's home and he was more amazed of how agile and comfortable Buio was on the ground. He makes quick sketches of Buio's little hops and gallops. Over time as Buio became older, the Italian found that Buio could be tamed. Buio began to respond to his name and even would come to the Italian when he was called. A special whistle was crafted and Buio was trained to fly on command, to return to his master and there was even a call for when dinner was ready. Which was unnecessary for Buio could smell the cooking of chicken blood. The Italian told no one of this, but he had set Buio out into the night to fly through the sky over the city. Sometimes Buio wouldn't leave the home until after midnight and always returned just before dawn's first light.

In 1854, news quickly traveled through the world that the land of the Rising Sun had finally reopened its doors to the world, thanks to the American Commodore Matthew C. Perry of the United States Navy. The Italian was excited just like the rest the world. A new world to explore and he hoped and prayed that there were bats in Japan! The Italian went to Japan, bringing Buio with him. Buio had been rather restless as he had entered adulthood and the Italian had hoped to go back to the Americas…to set his long time friend of the night free.

Japan was a truly unique place. The Italian took everything in, the sights, architecture and the arts. But, of course, he asked about bats. He was told about the bats in Okinawa, the Flying foxes that ate fruit and were very large. The most common bat in Japan was the common house bats that were found in homes, stables and barns; mostly hidden in attics or below the very homes of the Japanese, knowingly or unknowingly. The Japanese respected bats for they kept the insect population down. The insects were an annoyance to the farmers and the people themselves. The Italian, of course, presented to Japanese, Buio. They were stunned by Buio's appearance. He didn't have the friendly, long humorous face of the flying fox. They thought he was ugly and his shrieks chilled their blood! They were also alarmed when they learned that the bat did not feed on fruits or insects, but fresh blood. The Italian was sad for little Buio, for he was once again misunderstood. The little creature couldn't help it. That was the way he was. He reassured his little vampire friend that he was loved and was promised that he would take him home to the Americas were he could settled down and raise a family. The Italian loved Buio and his company and for brightening his life, even in the darkest of nights.

Buio never made it home to the Americas. There was still tension in Japan when the foreigners began visiting their homeland. Many Japanese still felt that the foreigner had no right to be in their country. Foreigners were being attacked. Some were either beaten or killed. It was their last night in Japan, the Italian and Buio at an inn. Buio was released into the night, what they thought was his last flight in the moonless night of Japan. Buio returned before dawn to his master's inn room and immediately was alerted to something wrong in the air. Blood was in the air, his master's blood. He knew the scent and taste of the Italian's blood for when he was taken from his home his master had took the risk of feeding him his own blood as they crossed the ocean. Buio located his master's body by the scent of his blood. His blood was cold. There was no life in his blood or body. His master was dead. Buio cried and cried until the innkeeper finally came to the room. The innkeeper shrieked seeing the dead man and the strange little creature shrieking in the dark. Buio fled into the night, heart heavy for the lost of his master. He circled the area, unsure of what to do in this strange land, till he heard a squeak. Buio followed the squeak and in mid-air he was met by a female Japanese House Bat.

The Japanese House Bat are as common as mice and sparrows and still live in Japan to this day. They are insectivores, feeding on insects. They had wide, short ears and a long snout. Not as long and canine as their Flying Fox cousins, but for feeding on insects they need that bit of reach and rows of teeth to catch their meals.

The female called out to Buio and lead him to a barn at the outskirts of the city. In the barn, lived her very small colony of sisters. Buio was very excited. It had been many years since he had been with a colony. He remembered very little of his colony in the Americas and the only female he could recall was his mother, barely. The females smelled sweet and when he was invited to join their huddle in the upper corner of the roof, he enjoyed their warmth and softness. Though saddened by the loss of his master, his heart was lightened and comforted.

Buio was the only vampire bat in Japan. But vampire bats are very adaptable. He didn't have a chose but to breed with the local bats. But Buio didn't complain. The bats of Japan were lovely! The sisters that took Buio and comforted him became his harem. They were unable to say his Italian name and managed to settle on Buiiro. Each female birthed him a pup by spring. The little hybrids were healthy little pups, half were male and half were female. It became their concern of what their pups' diet would be. Blood or bugs? It was through trial and error to figure out what their pups would need. Vampire bats are able to regurgitate blood to feed their young pups to wean them off their mother's milk. Insects were caught by the females and they regurgitated their meals to the pups. Most of the weaning pups took to the blood. The pups that were taken to the blood followed their father into the night and learn the techniques of locating their prey, how to approach quietly and how to feed.

Their little colony grew and grew and Buiiro took it upon himself to find a larger home in an area that could provide nourishment for his family and mates for their children. In his search, Buiiro felt a pulling sensation. Buiiro didn't know it, but the colony that he was born in were the spiritual servants that served the Bat of Life, Tzinacan. But, Buiiro wasn't aware of this spiritual energy within him, but, somebody else did. The local land god in the area Buiiro was searching had sensed his small yet noticeable pure spiritual energy and was intrigued by him. The land god led Buiiro to his temple and propositioned the vampire. The land god offered to protect his colony and give them a suitable home. He would bless his family for many generations, as long as Buiiro served him. The needs of an animal are very basic. Eat, sleep and mate. They live to pass on their genes to ensure that their genetics are passed on to their offspring. Buiiro and his children are the only vampire bats in Japan. Eventually, their colony would grow even larger and humans would begin to notice that their livestock are being fed upon. Even though bats of the Asian cultures are consider good and bring good fortune, he knew that bats of his kind are feared and misunderstood. Creatures that are feared are to be destroyed. To ensure his families' survival, Buiiro agreed to serve the land god.

The land god gave Buiiro and his colony a large cavern deep, deep in the earth. It was wonderfully dark, had fresh spring water and even deeper below there were hot springs! Buiiro service to the land god had him protecting the land itself from humans, evil spirits and demons. The land god opened and expanded Buiiro's spiritual energy. The energy within Buiiro grew and the land god taught him to use his energy to defend and attack. Being of the bat servants of the bat god, Tzinacan, Buiiro was able to connect with souls that still remained in the world of the living. Buiiro learned to purify and exorcize most evil spirits. As his power grew, he began to grow in size. His spiritual powers were even passed onto some of his children. Later, he and his children's magical and spiritual energies became strong enough that they were able to adopt human forms. With the ability to become human, the land god had Buiiro and his children to expand their duties to their land further. The bats continued to guide souls to the afterlife and heal souls that became evil.

Time went by and months turn to years, seasons came and went. Buiiro grew older and larger. Buiiro silently and without complaint watched as his harem grew old and passed away. His children too grew up, had pups, became old and passed on. But he remained. Continuing to watch his children grow and prosper. The land god continued to bless Buiiro for his services. Buiiro's home expanded and he was given his own temple.

The world around them began to change rapidly. Swords were replaced with guns; horses were exchanged for trains, bicycles and cars. Thankfully, the land of the land god, their home, remained green and free. The people respected the bats in the area and kept their land sacred. The land god was greatly pleased of the work of Buiiro and his colony.

Buiiro had hundreds of wives and hundreds of hundreds of children over the centuries. Buiiro wouldn't lie but he had some favorites over the years. Currently, he has three wives. One of them was his favorite (he wouldn't dare say this to their faces), her name was Nanako. Nanako was a happy, friendly vampire bat! She wasn't too bright…but her warmth was a part of her charm. Nanako, his favorite wife, gave birth to his favorite daughter, Nana. Nana was just like Nanako (possibly why she was his favorite). She was sweet, warm and charmingly not too bright. Buiiro loved Nana with all his heart.

So when the day came that she had told him that she had found a mate, he was stunned when he learned that the mate Nana had chosen for herself was not someone from their colony, nor an outsider from another! He would have been okay with it if her mate was from another colony. Yet, the mate that Nana chose for herself wasn't a bat at all…

It was a human named Iemitsu Sawada!
