This happens a few days after Hong Meiling and Flandre Scarlet got seriously injured by Koishi Komeiji in the Scarlet Devil mansion.

Satori felt guilty and went to the Scarlet Devil mansion to apologize. She also says that it is her fault if the two Scarlet Devil residents got injured.

After a long discussing between Satori and Remilia Scarlet,Satori accuse Patchouli’s familiar (Koakuma)to be heartless and evil. Patchouli didn’t believe her and it leads to a battle of bullet which Satori lose. Satori got injured btw.

The Scarlet Devil residents didn’t want her to comeback. Okuu and Orin were worried.

Patchouli :"Don’t let her comeback.”

In a cold tone Patchouli said. It was obvious that she didn’t want her to come ever again.

Orin :"Miss Satori ?!"

Rin looked at Satori,worried about her situation.
