Tatsuki was the tallest of the group even when everyone were kids, he has wings on his back and Hiroyuki Nishimura and the rest of the crew always asked him to fly with them, but he always responded that he couldn't since his wings were too tiny to be able to fly but promissed that someday he would be able to, this got recorded on Tatsuki's Mind. After he heard from Torahiko that he invited Hiroyuki to the village, he bought an old aeroplane from Shigure Tachibana and tried to repair it to fulfill his promise. From the very beginning of the party at the restaurant, Hiroyuki noticed his naughty behavior while drunk. After he sobers up, he explains to him what his job is. His father also fights for some Hiroyuki's flirt and depending on the choice, you can end with a headache in the restaurant without Tatsuki and Tappei around. After showing the Aeroplane to Hiroyuki, Tatsuki tried to make it work. However, the plane crashed after a few seconds of flight, making Tatsuki deeply depressed unless the Player confronts him. Player's choice can lead to a depressive story of Tatsuki left alone behind or make him happier than ever before, if the player chooses right. In a correct route, the Aeroplane will finally work and the happy ending will arrive. Tatsuki's scales are soft due to the fact that he uses the same Scales shampoo care as his mother.
