Hol' up- you got several things wrong here.
First off, the first generation's rain guardian name IS NOT Asari- his full name is Asari Ugetsu, and people from Japan starts with their last name and not first (As it is usually seen to be more formal and respecful) meaning his name is Ugetsu.
Secondly, Reborn and the other Arcobaleno doesn't appear until the time of Daniela (Vongola Ottavo)- As if they appeared during Primo's time, Reborn would've known about the Simon Famiglia and the dying will flames of the earth- Yuni would NOT be the Sky Arcobaleno at any point in the present seeing that she's the daughter of Aria, and Aria is the daughter of Luce/Luche. Since about 400 years have passed, I suspect that probably more than ten Sky Arcobaleno have passed away seeing that they do not have a very long lifespan. during Primo's time there were different Arcobaleno that isn't the ones we know. It is stated near the end of Khr that Arcobalenos do have a time limit and they do NOT last forever, as there seems to other Arcobalenos before them (The proof being Bermuda and the other Vindices, as well as the cave painting and the statements), and the current (read;current-not-current) Arcobaleno would know Talbot and several others who lived in the past like Elena, Magi, Simon, the first generation of Vongola and THEY'D MOST LIKELY know about Daemon's betrayal

Ah yes, the impeccable Uchiha language of Hnn

Please update! Your story is getting interesting! . I wonder what would happen next .

Is 'Unknown' a canon character or an OC? (O.o) because, really, the only character I could think of that could be them is Julie *sweatdrops* but he's from the Simon Famiglia so I'm pretty sure he doesn't count.. For a good bit, I thought it was Colonnello since he says 'kora' and they're referred to as 'Cora' xD
Maybe Bianchi? (O.o) or maybe it really is an OC, I'll never know xD

wow this story is really good.
i really like it.

wow. this is a really good story.
i really like it.

welp figures there would be two reborns or is it reborns ancestor like Gitto is to Tsuna. Oh what happened to natsu roll appeared im guessing mukuowl is with chrome so were is Natsu

Wonder... When Tsuna being bigger and older, I think he was not look-like Giotto again, but like his Twin.

PAPA reborn is real and i will fight for it!

Well, Tsuna is an adult, but unlike them (I think?) he actually got the mindset of a seven-year-old from time to time.

Neat :-)

Thank you for sharing this with us :-)

This is one of the greatest first chapters I have read in a while. Thank you for sharing this with us! :-)

(By the way tier and tear looks like typing error, but is actually quite amusing as "Tier" means animal in German. So, you basically said there were animals coming out his eyes XD

I really find this story fun to read! Sad that it’s now on Hiatus but thanks for the update! Will keep up with the updates from now on! I really hope your family is alright!

it's so... short chapter.
