Alright, so far:
1. I like how supportive Riyou and the others are for a newbie. They're being considerate and welcoming, praising him instead of just ganging up on him. That's what builds up connection and should make Rudo feel wanted, needed.
2. Never before have I seen fighting with giant scissors, especially using feet to do so xD It's insane, suitable for Fire Force's assistant.
3. I'd like to see more distinction between support and regular Janitors. Maybe they're also for carrying supplies or gathering resources, while regular Janitors are more for fighting and scouting?
4. Rudo needs to experiment with his Jinki more. So far, he can't really know what the items he touches turn into and that capabilities will they have. Maybe Riyou can help him in that department. Maybe he can direct his thoughts and feelings better and THAT will shape the items to his needs better too?
