Fuku-chan, Rikka's new space alien pet, has gone missing, and he's not just a harmless walking giant mushroom. Can Sekine stop him from devouring her friends, both figuratively and literally?
Fuku-chan, even if you never come back,
Auch du, Fuku-chan.
Selbst wenn du nicht zu mir zurückkehrst,
Fuku, aunque nunca vuelva a verte,
Fuku, aunque nunca vuelva a verte,
Mon petit Fuku,
même si tu ne me reviens pas,
Fuku, anche se non tornerai mai da me,
Fuku-chan, mesmo que não volte,
Фуку, даже если ты не вернёшься,
