Shipping aside, Chuuya is viciously protective of those he considers his people. Dazai is one of his people. And Dazai is so badly injured rn and imagine if Chuu still is under the vampiric influence and he hurts him more before breaking out of it. Or if he isnt under the influence he'd be so pissed off.
We've seen how he reacts to Dazai getting genuinely hurt and this feels like its gonna hit like an atomic gut punch.
Can't stop thinking about the Collector just being a little dude. A little guy. Pushed away from his family. Watched their Titan friends get killed by other collectors. Got trapped in a disk. Had the horrible realization of what mortality is. Learned how to connect with people. Is a literal child.
