Let's post some (joking or serious, either way) "rules" of anime or things that always happen in anime.
Rule: If the girl looks like she's 20, she's probably 15, if she looks like she's 12 she's probably
18.
Rule: Gravity does not exist in anime, characters merely choose to stick to the ground and when they want to, they will jump 100 feet in the air (note: everyone has this ability)
:)
