When i read the game description in top, i see the different between rank A and S is just side story in rank A isn't complete, also they aren't feel fully develope so yeah they maybe does not have different in term of Power like other Gacha, and you think that Mc is OP? Isn't he should be?? Like i mean, he is MC, MC of a harem fantasy world story which need a fucking strong OP Mc in general, or maybe because they treat Mc like other A rank, still not fully develope, doesn't have complete story which is kinda true because his story only finish when the dev really put an end to the game so yeah... Maybe he will just sitting in A rank for a long time
