@MrSeyke rough abstract : Maho was badly injured during her expat time in Deutschland. So when she's back in Japan, she was hospitalized, received surgery and seized her participation in Sensha-Dou (戦車道). During her release from the hospital, she met Anzai who invited Maho to the apartment nearby and proposed room-sharing so Maho could go for rehab at the hospital more conveniently.
In the meanwhile, Mika often drops by when she's in town. Making live stream talk shows with Maho and Anzai.
((Akiyama and Erika are seeing each other by the way))
Somehow, although Maho became fully recovered, she received warning from the physician that the wound would relapse one day, which deeply bothers Maho about her life and career - - what she has left without Sensha-Dou. Thus Maho brought up her depression and said that she might go for a self-exile. Anzai got truly depressed, which in the later reveals that she's very fond of Maho and felt connected to Maho's uncertainty.
After pulling herself together, Maho is back in the field as a pro. During her press conf, she said that - - "I've been putting Sensha-Dou above everything. And I was quite lost. Now I have people behind me, which become the support for what I'm going to do."
Miho, walking in the street and sees the big Telly, says - - "Well, I'm kinda jealous about that."
One day, the group of three are enjoying their holiday, Maho took a picture and tweeted : "Celebration for my full recovery."
