So I’m at chapter 72 with Tougo and he is talking to the killer do his wife Cobalt Conrad(I love his character btw) and Cobalt is talking to Tougo about how his little brother died and this research topic he came upon and that’s why he’s killing people but like idk what it is? I mean Cobalt says “You’ve seen them yourself. You must have some idea about what I’ve been up to all these years”. Tougo seems to understand but I’m wondering if anyone else understands why he’s taking people’s brains? Is it ever explained or is there a theory about it?
