That lie bit his ass really hard lmao. Also he has now two absurdly powerful sisters (other is temporary at least lol), but I'm pretty sure Maya-nee will track him out by his smell before he get's his ass fried. I have a feeling it'll end up him taking the credits somehow as her sister saves him yet again and that demon general tailing his ass due to it lmao.
I thought she was the demon lord too, damn I guess the lords (6?! that's a lot lol I wonder how humanity survives here xD) probably absurdly powerful then, like the one on overly cautious hero and their generals aren't no slouch either. I wonder if Nee-san can handle this or maybe Asahi will need to gear up too as I can see a situation where he'll see Nee-san get hurt badly in one fight I'd wager.
