Baby harp seal mascot character Sirotan is making an anime debut in a 24 episode short-form series entitled Sirotan: Sirotan ga Ippai! (“So Many Sirotans!”)
Aoi Yūki provides the voice work for the Sirotan ga Ippai! series, while the theme song is provided by rock band Sankaiten to Hitohineri.
Described as a “soft and fluffy” story, the Sirotan ga Ippai! anime features the adventures of Sirotan, a baby seal who likes to nap and dream about many different relaxing activities.
