MikaMitsu

MikaMitsu is the het ship between Mitsuba Sangu and Mikaela Hyakuya from the Seraph of the End fandom.

Canon
Both Mitsuba and Mikaela rarely interact with each other, but appear to be on good terms with each other.

Mitsuba sees a group of vampires at the 5th Street intersection, one of them being Mika. After being promoted following the Battle of Shinjuku, she is boldened by the fact that she can use her new promotion to help Yu find Mika.

When Mika attacks the Demon Moon Army, Mitsuba along with her squad, defends Mika from being killed. Mitsuba raises her axe to defend against Mika, but he pushes it away. The action distracts him and Shinya is able to stab him through the chest, alarming Mitsuba. Later, she helps Mika escape with Yu. When the two come back, she and Shinoa are surprised but end up using his help to escape from the Krul's vampires and the rest of the Imperial Demon Army.

Mitsuba, Shinoa, and Kimizuki listen to Yu and Mika's interactions within the cabin. When they approach the group, Shinoa hands Mika a bottle of their collected blood and await for his response. He takes a sip and bluntly says that it tastes disgusting. Shinoa worries that "the unchaste blood" might've gotten into it, making a suggestive glance at Mitsuba. During their discussion of what their next plan of action should be, Mika suggests that they could save Krul because he believes that they can trust her. Mitsuba agrees to the plan.

When Mika loses both of his arms, Mitsuba helps him put his arms back on his body. When Shinoa and Mitsuba see a naked Ferid, they both try to hide behind Yu and Mika.

Ignoring Shinoa's comments about the first vampires, she tells Kimizuki to floor it and to continue on to where Yu and Mika are. Mitsuba is also later called upon to help put up a barrier in order to turn Mika into cursed gear. When they are finally told to relax, Mitsuba, Yoichi, and Mika casually look around.

They are both shown to have a fondness for Yuichiro and have blond/golden hair. Mika is a Taurus (May 1) and Mitsuba is a Cancer (July 7), making them extremely compatible. They have a height difference of 18 cm.

Fanon
The ship is a rare-pair within the Seraph of the End fandom. The ship sailed due Mika's and Mitsuba's extremely opposite personalities, Mitsuba being nice to Mika and helping him to put his arm back on his body, helped. In Mitsuba's official realtionship chart it's mentioned that what she looks in the opposite sex (it's implied, it's for a romantic partner) is someone who she can rely on as a leader. Mika seems to be the type, who could lead people good, which is another reason why the ship is shipped.

In fanfictions, Mika's and Mitsuba's relationship is often like it is in canon, Mitsuba is being nice to Mika, making him warm up to her and he falls in love with her because of this. Despite being a rare-pair, the ship got some attention, as the ship is often shipped alongside YuuNoa, the ship is also popular among popular who would like to see Mika in a het ship. Nontheless, both character's have several more popular ship's, namely MitsuNoa and MitsuYuu for Mitsuba, and MikaYuu for Mika.
