Tatsuki Midoriya (翠屋 辰樹, Midoriya Tatsuki) is one of the 8 playable routes and one of the 9 choices to be Hiroyuki's boyfriend during the events of Morenatsu. He's Yukino and Tappei Midoriya's son; He works with his father as a Carpenter on the company that the family have from ages with Tetsuya Inoue, Chuukichi Mori and Akira Nikaidou. He likes painting, however it's not really focused on it. He's very joyful and happy similar to Torahiko Ooshima but a bit more calm and pacifist, both are like best friends. Tatsuki is obssesed with Alcohol like his father but since he's a Dragon, he has a high resistance to it and gets sober after a few minutes.
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.
Tatsuki's personality is very joyful and happy, aside from his alcoholism, he's a very nice person, always able to help people and cheer up the loneliest soul. He can be very naughty if he's drunk, or still be if you became his formal boyfriend. It's unknown if he's really a virgin as he states, due to the fact that while he's drunk he becomes a real pervert and he doesn't remember what he did after sobering up. Sometimes he drinks because there're some things that he cannot say while sober. He loves his family. He doesn't feel shame about anything, to the point of going out naked without blush, but he doesn't have anything to show since Reptiles use a cloaca where they hide their genitals. He's very emotional to the point of being very happy or very sad and if someones challenges him at something, he will do it without hesitation. He's sensitive about his belly, implying that Dragons naturally gain weight, it's not that he's fat. He can get easily excited about something to the point that he's very dangerous while driving. He has been in accidents already.
Short Description: He is a lively and cheerful dragon. As a dragon, he has a large physique, though he's a little worried about how much his belly has grown lately. His family's business is carpentry that specializes in shrines. His father is the boss, but Tatsuki is working hard every day to become just as qualified. He dreams of being Japan's best craftsman. Kind to everybody, he is like a good big brother to everyone because he likes to help. However, little often comes out of it and he usually fails at both his job and private matters. He is the only member of the group who can drive, but a car is like a dangerous weapon when he drives.
Tatsuki wears his job's clothes which include: a blue jacket that doesn't cover his chest and belly, brown shorts which are held by a black belt and some handmade sandals. He has black hair which continues all the way down his tail, green scales which are followed by a light yellowish pattern that covers the chest, and parts of the tips that sun doesn't reach also the soles of the feet, he also wears a red band on his head. He has big eastern-dragon-like horns. He has tiny eyes and because of this, the eye color cannot be appreciated, he also posseses big eyebrows which are 100% muscles with no apparent hair.
Physically, he's a Musclegut, even if he posseses a belly, his big muscles on his arms and proeminent abs are noticeable, this is also stated by Hiroyuki, there are two fangs that are always visible, since he's a reptile, he posses a cloaca where his genitals are cointained.
Tatsuki claims that he's a virgin, which, given how sexual he gets when drunk, is unknown if it's actually true.
Tatsuki's muscles weren't that prominent in the development state, also, the scale of colors are more darker and the pose shown is missing in the game database, 4 fangs are visible instead of 2 and his posses claws instead of nails, the direction of his band got inverted and his shorts didn't exceded the belt's size.
Tatsuki posseses 3 joke endings, one where Chuukichi becomes a 50 foot tall demon that Hiroyuki must defeat, one where he's a robot who self-destructs in order to save Hiroyuki from being killed by Shigure and the other where's a self-destruct button in the airplane, that actually blows up the airplane. In 2 of the 3 joke endings, Tatsuki dies, however in the Chuukichi demon ending Tatsuki gets captured by Chuukichi.

Tatsuki has the largest genitals, and largest compared to his size.
Tatsuki's profile is used as the Morenatsu game icon.
Tatsuki is the only character in the game (outside of his father Tappei) with animilistic genitalia. His penis is human-shaped, but retracts and extends out of a cloaca, and his testicles are fully internal.
Midoriya Tatsuki literally means Green-Shop Dragon-Tree, a recall to his species.
There was a scene in the trailer where Tatsuki and his father are engaging in bondage. It's unlikely if this is canon, but given how both of them appear to be drunk, it brings doubt on Tatsuki's claim that he is a virgin.
Tatsuki's hair is blue in game, but is actually black. The blue color is a stylized way of standing in for black in many comics and animation.
Tatsuki vividly talks about "Sachiko" while having a dream on the bus ride home from the beach.
