Artist's comment.

「ボツキャラ。気に入っていたけどイメージと合わなかったのでボッシュート。公開許可をいただいたのでぺたり。」
"Discarded character. I liked it, but I couldn't get the image quite right, so it got tossed. I managed to get permission for the public, so here."

A discarded character for 7th Dragon, I guess?
Would this warrant that tag, then?

'Grats to whoever used the word "gradation." Your vocab is excellent!
