Munechika Nakatsugawa (中津川 宗近, Munechika Nakatsugawa?) is a crew member of <Fraxinus>, a ship located
15,000 meters above Tenguu City. He holds the title “The Dimension Breaker”. As a member of the Fraxinus crew, Nakatsugawa helps vote the decisions that Shido makes when he confronts Spirits. According to Kotori, he is a man with over 100 waifus, of course, all are 2D characters of animes and games. For short, he is an otaku who only shows love for fictional girls.
Nakatsugawa has short brunette hair that spikes out in the front. While onboard <Fraxinus>, he wears a dark green suit with a black tie. He also wears glasses with a red rectangular frame. Nakatsugawa has an outgoing personality, being one of the more passionate members of <Fraxinus>’s crew. He is very driven about his Otaku hobbies, which helped out Shido and the others when they needed Ratatoskr to create a doujin and booth for Comico in order to compete with Nia. He is also a big fan of mecha, complaining to Shido about missing <Fraxinus> when it is under repairs. Much like Nia, he is in love with 2D. However, he also tells Kotori that he is also fine with Seiyuu (voice actors). Despite being very passionate, he is also very embarrassed about his past as MUNECHIUKA, telling both Kotori and Shido to forget about it when they heard his old name.
