-"Sent to another world"
-Love conquers all
-Friendship conquers all
-Kindness is stronger than evil
-Girls fighting over one guy
-Hate and anger creates visible evilness / mutation to evil
-Useless supporting character who's only goal is to yell out the main character's name
-Spoiled Princess role
-"There's good and love in everyone." sez the main character. Well, except for the main evil boss.
-Less evil characters turn good.
