Sore wo Ai to Yobu Dake

One vote = the voter's rank power: D +3, C +5, B +7, A +9, S +11, S+ +15 on a like; dislikes drain C −2 up to S+ −7. On green (6–10) it pours into this anime's tank — on RED (1–4) it's the mirror: a like TAKES the rank's value off the tank, a dislike hands it back (an S+ like on Trash takes 15 XP, for example). 5/10 Mid is neutral: it never moves XP. Dislikes and likes on RED reviews require C rank (500 XP) — D can still like green/neutral at +3, and a mobbed anime can go negative.
