TatsuMayo

TatsuMayo is the slash ship ship between Tatsumi Kazehaya and Mayoi Ayase from the Ensemble Stars!! Fandom.

Canon
Tatsumi and Mayoi are both in the group "ALKALOID".

Since ALKALOID was created, Tatsumi had been interested in Mayoi, calling him beautiful, helping him and pretending they're Hiiro's and Aira's parents. Mayoi usually gets overwhelmed due to his behavior because he thinks he isn't worthy of someone so pure due to his poor self esteem, and he apologizes a lot, while Tatsumi denies his words.

During HiMERU's event scout Romantic? Date Mayoi along with Kohaku helped Tatsumi and HiMERU, who needed to record a fake romance scene for a game. Tatsumi got too excited with the idea of a date because of his own lonely childhood so he brought Mayoi to a lot of shops and made him wear a lot of clothes, went to the arcade, karaoke, etc without realizing how tired Mayoi was because he thought both of them were feeling the same, Mayoi told him he was actually enjoying it too, but he had limits, so Tatsumi promised he would do better the next time. This reached the point where Mayoi felt like his ears and heart had melted because of Tatsumi's sweet word during the day. Mayoi also was uneasy when Tatsumi and HiMERU were acting too closely.

During main story Hiiro asked Mayoi if he was getting engaged, Mayoi said he is cursed to "never be wed to the person he loves", to which Tatsumi replied if that were a RPG he would be the priest who breaks that curse.

During SS / 1st Stage: Satellite event, Tatsumi had mentioned that he “always complains to Mayoi and tries not to hold back or keep everything to himself”, showing a clear trust in their relationship. In the same event, he also called Mayoi “a great mother to these kids (Aira and Hiiro), and an irreplaceable partner to him”, causing Mayoi to get flustered. He’s also praised Aira and Hiiro by calling them “his smart kids” while patting Mayoi in the shoulder, but mentioning that he shouldn’t call them that since “they weren’t their kids”.
