Luna " wow, that's older , then grandpa old" she said form shock

Leo" you must have an easy time writing history reports "

Luna " wait the masked ninja guy said demons are good , but how can that be when there's all of those stories about demons killing humans" she asked

Yusei" Demons don't kill humans unless provoked , for instants do you two now the story of the 9 tailed fox" the twins nodded yes " well he attack because some humans for that village killed his new born kits who's mother died giving birth to them when he returned to them after hunting only one of his kits was alive , he just a attack to avenge his family "

Leo putting his arms into the it happens pose" well there's two sides to every story " then the sound of sector security's duel runner's sirens filled the air

Luna " what's going on" she asked

Luna " Yusei why are you here" she asked as she let go of Yusei

Yusei " I thought you would like to know more about me "

Leo" I know I do" he said as he let go of Yusei

Yusei then told them why he came to Noe Damiano city , about his parents , Jack , and the hidden demon village that now has smaller village allover the world one of which is under the satellite

Leo" so Jack's part cat demon and part wolf demon" Yusei nods yes

Luna" and he's here because he stolid your first duel runner and stardust dragon card" Yusei nods yes again

Leo now crying as his sister Luna started to cry " That's a grate story Yusei but who knows what'll happen to me and Luna now"

Yusei " I think I now, Luna Leo , I was thinking about adopting you two"

Luna wiping her tears " thanks I would love to have a father who cares about me but there's noway the city would let you "

Leo putting on a face smile " you took the words right out of my mouth "

Yusei " Luna you forget I'm a ninja , I can work the system to my favour " he said making Leo and Luna smile

Yusei" so once again would you two like it if I adopted you , but be warned if you yes , your DNA will be changed making us blood relatives , also some of your humanity would be replaced by animal instinct ,mean you would be over powered by strong urges and instincts and if you don't learn to control the older you get the more powerful those urges will become , so do you two still me to adopt you" the twins nodded yes

Yusei smiling as he made some hand signs " Good now hold still" and with that red charkra came out of the twins bodies and engulfed them for 5 seconds before it stopped and when it was gone the twins now had green fox tails, there human ears had been replaced by green fox ears and there nails now were claw like

Leo then saw his tail swinging back and forth in a mirror , this made him start chasing his tail on all fores

Luna sweet dropping form this " ow brother "

Yusei laughing " that's what I meant by being over powered by strong instincts and Urges , and the faked that you're not chasing your tail Luna means you can control your self better then your brother " he said as Leo coot his tail in his mouth and started to nibble on it

Yusei to Leo " Son I'm going to tell you what my father told me then I was your age and I nibbled on my tail , keep it up and you're going to throw up a hair ball" this Made Leo spit his tail out of his mouth " It still works after 400 years "

Luna Looking at her one tail and Yusei's 7 tails " Dad why do we only have one tail"

Yusei to Luna smiling form her calling her dad" Luna tails are a symbol of power , the older you get or when you do some thing to earn it you get and new tail and your power will double "

Leo " dad why to I make the fire ring thingy " he asked straight to the point

Yusei" Leo that's Fox fire wave , and you need 6 tail to do it now we have some work to do to the city to let me adopted by there laws so you both get two more questions " he said to his new kits(Luna and Leo)

Luna " what's fox fire" she asked

Yusei making a fire ball appear on his left index finger making the twins jump back" this is fox fire it's the base for most of the attacks a Fox demon can do and it can only be used by Fox demons of kitsunes for short "

Luna" what do you mean the base for most of the attacks a fox demon can do" she asked

Yusei " every demon and hanyou has to elemental powers , for fox demons it's fire and Lighting " he said as he made the fire ball disappear as a ball of lighting appeared in his left hand " There's elemental attacks , normal attacks and and fighter attacks , elemental attacks can be used by both humans and demons but humans have to make a lot of hand signs to do it for demons you just have to say it's name and put your chakra in the right place "

Leo puzzle " what's Charkra" he asked

Yusei" chakra is the power that's in ever living thing you may now it better as chi "

Yusei " now as I was saying normal attacks can by used by anyone , but both Humans and demons have to made hand signs for it to work " he said as he made a some hand signs and when he was done he disappeared in a cloud of smoke and reappeared behind the twins in another cloud of smoke

Yusei" and Fighter attacks are just normal every day fighting moves , that have be made stronger by adding Charkra to them"

Yusei to Leo " Son you have the last question "

Leo " will you teach us how to do those attacks " he asked in a hipper tone

Yusei " tomorrow son but right now it's late , so you two beast be off to bed "

Leo heading to his and his sister's bed room " fine"

Luna fallowing Leo " Good night Dad"

Yusei smiling" Good night to you two " he then thought Dad I now your smiling right now and so is mom
