Petopeto-san - S01

After centuries of conflict and misunderstanding, the Japanese have finally welcomed youkai into their society. To encourage integration between species, ordinary children start attending school alongside paranormal creatures who look almost human. Shingo Ohashi realizes he is falling for Hatoko "Petoko" Fujimura, a half-youkai, half-human girl. Her powers include an uncontrollable cuteness that charms everyone around her, similar to a low-power succubus; getting stuck to anyone who touches her bare skin, which only ends when she falls asleep; and the ability to vanish down to the molecular level, something she can mostly control.
