Torajirou Asuka

Japanese voice actor: Shiho Kokido
English voice actor: Hopefully, there will be one.

Not yet out of elementary school, Asuka, is the youngest of the group with an Appli Drive.

Asuka is a famous App Tuber (like Youtube) who goes by the name of Astra. (I'll be calling him that for most of the episode summaries.) Astra's partner is Musimon.
