I hope he chooses one. I don't feel like a harem works here. Uryuu is being put through a heavy trial right now. Unless something huge happens, it would make this whole arc meaningless imo. Routes are ok to me but feels a bit lazy. I love that Gotobun had the guts to choose one (even though it wasn't the quintuplet I wanted T_T). The god subplot is still there. I wonder what that'll bring.
