Every anime has one. Every single one. Doesn't matter if it's a psychological thriller or a mecha series, suddenly everyone's at the beach in swimsuits for no plot reason. Obligatory Beach Episode Body helps you smell like a suspiciously convenient beach trip instead of someone who hasn't left their setup since the season started. Apply before cons when you're cosplaying beach episode versions of characters. Your hygiene doesn't have to be filler content. The scent is canon. Your shower schedule is not.
