Why did my parents die, then?

Ah...

It's a matter of aptitude.

The main component that turns a human being into a Breaker is something called 'Shard', found within a Breaker's body.

The invasion of 'Shard' into a human body causes infection, and it takes over the host's brain.

However, some people show symptoms of rejection during the infection phase, killing them in the process.

Your parents' case comes under the latter scenario.

So there's nothing we can do about it...

In this case...

I'm sorry.

Do you want

revenge?
