For celebrating the fall equinox. I was thinking which Boktai character has fall impression and he came up. Probably he has flame element so. His official solo art doesn't show his pupil and ears, but you can see them in the group art.

秋分のあいさつ、白装束の少年。秋っぽいキャラって誰だろうと考えたらなんとなくこのひとだった…フレイム属性のせいかな。カラス感は薄い。公式絵だと瞳がなくて耳も隠れていると思いきや、愉快な仲魔たちとの集合絵だと赤い瞳とやや尖り耳が確認できます。
