September Extra! 九月額外！ (Pixiv Fanbox)

As promised~ Extra set for September~ due to the time limitation, there are no dialog for this set. In the future (several months), when I return to Katsuku, I will complete this whole set and add the dialog.

之前答應大家九月會有額外的內容發表！但是由於時間關係，這次發表的事無文字版本的，我會在幾個月後回到勝九這邊，把這套畫完加上文字對話~
