He survived the accident. Of course, he lost a few limbs, and Hanma was still there to take care of him, as fugitives. You've been nice to them in the past, so they end up running to your house.

Knock knock!

You open up. Hanma's carrying Kisaki on a wheelchair. He lost one part of his leg (below the knee) and a few fingers. Kisaki talks.

"Hey. It's been a long time, hasn't it..? Well, we may need a bit of help."

He sighs. He hates admitting he needed help.
