A special booklet released by Kodansha on October 9, 2018 bundled with a special edition of Volume 3.

*A collection of stories based on the Azur Lane mobile game.*

This is the official comic based on the game of the same name. An all-girl's school is preparing to consolidate with another nearby school, which will make them co-ed. Uryuu Shingo is chosen to be a male 'test student' at the girl's school before they officially merge in the following year. On Shingo's first day, he learns that many of the girls are not happy about the coming merger. Specifically, Seno Airi is staunchly opposed and refuses to welcome him to the school. Some of the other girls are friendly, but Airi has a lot of power over public opinion. The truth is, though, that Shingo has met Airi before. When she and Shingo's little sister got lost, he helped them find their way. Airi seemed to like him then, back when she didn't know he was going to be her new male classmate. Maybe he'll be able to win over Airi, as well as all his other interesting female classmates! (Source: MangaHelpers)

I met my childhood friend again, and she had become a beautiful and innocent-looking girl. *"It's been a while, Hayato." "Haruki, is it?"* In the past, I used to play in the mud with my childhood friend in the countryside. When I saw her again, there was no trace of the bratty boy I thought she was back then.

The manga revolves about a mermaid named Muromi, her travels and her quirky personality. She speaks with a Hakata dialect and she thinks sea water fish are better than freshwater fish. She has a sweet tooth and loves sake. She's also said to have been living for thousands of years (although she has the appearance of a teenage girl with a fishtail). Join Muromi on her adventure, as she gets caught in high school student Takuro Mukojima's fishing nets, as she meets more friends, new and old, and enjoy their weird but hilarious conversations. Or, you could just watch her bother Takuro on his fishing days with lame gags, just for laughs

The protagonists of "Chie Aru Koibito," Ushidome-kun and Shirakaba-san, are both intelligent class representatives who judge things rationally. Even though their classmates extol the two as a perfect match, Shirakaba-san declares that she "doesn't have even a second to lose herself in love." Ushidome-kun is honestly shocked by this, but he also appeals that he is "not in a state to fall in love," which upsets Shirakaba-san. They are both too conscious of each other, and the rationality of the two explosive people is on the verge of collapse. This is the love story of a male and female honor student who cannot be honest with each other and are tormented by their own worldly desires.
