Both Hidetoshi and Avenger aren't participating in the event. But Hidetoshi will be totally willing to help out and partner up with whose who are (as long as they're not hostile) to search for candy! The candy he cannot actually perceive, lmao. But he knows how this works, so he'll try hard to find some.

He wouldn't take anybody's candy, until towards the end of the event, where his sense of self-preservation will likely override that. Gonna have something for those shadow children to eat after all!

(He's going to get so many flashbacks guys.)

And Avenger will not be interested since he can't perceive the candy either. It's very likely he'll just be killed by shadow children at the end of the event or something tbh idk
