Even though he's a lot older than Ichi even if he's only in his early 30s, Jiji knowing all about Ichi's traumatic senior high experiences and his resemblance to one of the bullies shown's definitely fishy. That only made me wonder more about who the guy really is. It's sad to see how Ichi was torn apart between sparing and killing Kaneko after all the kindness he'd shown him...
Kakihara and Jirou found out about his location so I hope that Kaneko wouldn't be able to get to the scene on time.
