Either naruto and make come from the senju clan with wood release and hinata or ino as love intrest also highschool dxd would most definitely be interesting but if you do a harem dont add rias and actually put some devils in check and let them solve there own problems to many fanfics where they either train them to fight rizer or outright fight him themselves but you could join sona group that would be interesting
