Series: The proof of trust (ichimonji rasetsu)

https://www.pixiv.net/artworks/68639753

Seemingly a prequel to Efforts in Business (pool #1893).

Original title: しんらいのあかし

Artist's commentary:
せっかくなので プロフ絵のバックストーリーを考えてみました
赤ゆのまーちゃが一番好きです

TL:
I've tried my best to think of a back story especially for the illustration.
I love ko-Marisas for the most!

(This pool was once used for holding duplicates of 「Forbidden」life (pool #1942), and as the duplicates were merged into the old pool, this pool is now used for a different series.)
