Why is Atushi so obsessed and smug with his Rocksion dream when it's originally jus his band performing+Hina levitating the band members using her powers.
So wtf did he reject the girls, in the first place ,even a normal band would have each member in charge of a role /instrument, so his rocksion would essentially mean a normal band + an esper illusionist. So him rejecting the girls at the start was just plain stupid and him being a twat.
Especially since he's trying to gain esper abilities, it feel like the whole rocksion thing is a farce for him to try and gain abilities for himself. If performing his rocksion was the goal having one of the three girls help would suffice, even if they're not gonna put up his bs and perform with him all the time, know hina he could just have an yearly performance and give some of the earnings to her, and I'm sure they would still have enough profits, or worse come to worse ask Hitomi for help with the sales
