Man, really feels like a season finale episode. That one image slowly adding up as more of the team joined the attack was just amazing.
Also, goddamn that demon king form looks way better than what I imagined from reading the novel.
I mean, she is supposed to be the last boss (hence the manga's name) in the original otome game setting. Pride using her "last boss" abilities this early into the game's story would naturally make it look OP.
Makes me wonder if Ed had similar "important" relationships in the other 99 worlds. Not necessarily romantic, but just bonds strong enough that he'd consider staying with the other person/s or bringing them along in world-hopping.
