Shiro as in Shiro from Voltron? The Black Paladin? That Shiro?

Whoa, this is so interesting! Continue!

Yey an update!
You know..the conversation between the three of them are really funny..hiro is dominant in kuro than shiro..lol
I wonder how satoshi can see the eyes difference..maybe he has a spiritual power in him? And I'm also wondering if by any chance tadashi will find out about them before he dies later..

I would like to point out that jumping to the future then jumping back does tend to gut any suspense in later chapters as you know everyone is going to make it out ok. Just my two cents.

The story has intrigued me enough to catch my attention. Carry on!

Soooooooo basically..kuro and shiro have the same look as hiro?with eye colors difference?i wonder how he will live with those two in him..and i wonder if tadashi knows too..
by the way..i know i am a slow person..but damn i just realized that tadashi will die too in this story after i remembered the third chapter ToT

This is a great story please update soon!

this is soooooooooooooo interesting. MOre pls.

well this is certainly a fresh new perspective in the big hero 6 fandom. this has an interesting premise and pretty well written with good and realistic character relationships. I wonder if we will get to see if anyone else has what Hiro has or it will just be him and if this will play a role in hiro's later life when he becomes a superhero if that happens that is. keep up the good work and keep on writing.

Is this a side story? Actually in my perspective its not good to make a side story with a huge time difference set like this..except if the main event has passed and you decide to make a time-skip with some details..just feel a bit "miss" or "odd" for me..
but from the other side..this is quite interesting..silver makes me think that it's not hiro but shiro instead..like hiro has two other personalities because of the accident..i think this chapter kinda gives me a glimpse of hint on why the title is cerberus..
ps: pardon my english because it is not my main language

This sounds interesting I wonder what will happen to Hiro and what exactly more is. I bet he's either a cyborg or has a pacemaker.

Hehehehe I love the little being in side Hiro's head. their personalities are so unique and I love their interactions. thanks for the quick update! the second chapter was amazing and I loved how you integrated the feelings of the characters into the story without flat out saying, he was sad or something like that. It was really nice to read!

the first chapter makes me shed a tear..and the second one makes me giggling like an insane woman..those ro-ro brothers (sorry i come up with this thing lol) are so funny! Hope to see update soon

im not sure exactly what the summary has to do with the story yet but I'm to find out! I loved your first chapter and I really liked that in this case of mean words being said, it wasn't hiro being a brat that caused it. and people say a lot of things in anger, especially when that anger has been built up over long periods so I can see what tadashi said being something that might be thought. anyways, I'm so excited to read your next chapter! thanks for posting

Okay I just skimmed through this. One criticism here.
Tadashi would never EVER say those things to Hiro! He would be proud of him, and would never hate him.
One of the things I mostly love about him is his affections towards his little brother.
