usually in anime, there are four types. you have:
usually this is the one that you love with all your heart, even if they are the bad guy. you like them because the way they act, talk, power/enhancement(if they have one) and is just all in all, the favorite. which can be more than one character
not a character who simps over someone but a character that people simp for. is there a name for that kind if person? simp victim? simpie? you get my point. you will do literally anything for this person.
pretty straightfoward. you hate them because they either did something you didnt like or you just randomly hate them.
can be 2 years old to fucking 1000 years old, doesnt matter. you will do anything for this character and if they get hurt you will go mad. how could anyone do that to your baby?? your baby gets whatever they want and you will give it to them
