Obviously we just gotta start with Asta’s dialogue. Its cringe but he’s also not wrong. We know he can read Ki and we know Ki can tell if someone is lying or not. He says Liebe cant kill a human but a human is not a devil. We know he wouldn’t kill someone because he loved a human
We see him take Asta’s hand and knows he’s his “brother.” We know hes filled with malice and dark emotions but they were tied to an attachment he made with a human. Unlike other devils that are described by Yami as pure malice
We then even see Nacht accept Asta as correct in his decision. As for why? Idk. It’s likely because he developed a friendlier relationship with his devils when at first he likely just treated them as basic slaves, but even so, his philosophy goes directly against that belief
Nacht is someone who flip flops around in his words and the tone behind them. He agrees with Asta, yet he hates the Black Bulls. He calls Asta stupid, but he says he’s right. We need to know more
I also like it when Tabata decides to not put a background in the panel like Kubo does (even tho it might just be laziness).
