Akki is Tama's younger brother. He is more quiet than Tama and gets along well with the kids in the neighboring village, who look up to him with respect. He is often seen playing games on his handheld console, tending the general store, and making phone calls for Seishuu. Akki is surprisingly good at finances, to the degree that even Kawafuji asks him for help with investments and playing the stock market.
