Hatsu

"At least I don't wear women's ear decoration!!!"

- Hatsu to Koon

Hatsu is a Regular and a "devoutly" practised swordsman. He teamed up with with Anak and Ship during the first test on the 2nd Floor, and later signed Koon's friend list. He is a quiet and calm warrior, who has been making good progress in the tests merely by doing exactly what each test entails.

Appearance and Personality
Hatsu is a dark haired boy. He is well muscled, although very thin. He wears a black and maroon robe with an orange cloth around his waist.

He is generally very cool headed and has only lost his temper a few times. He can be fairly social, but is generally quiet. Not much is known about his intelligence, but he does seem to have some ability in battle tactics.

Tower of God: Part 1
In Part I, Hatsu appeared on the second floor with all the other Regulars. He encountered Anak and began to fight her. Ship Leesoo then turned up, but both Hatsu and Anak completely ignored him. Subsequently, It was announced that the Regulars had to form teams of three, and Hatsu and Anak stopped fighting immediately and teamed up. They continued to ignore Ship, but as he grabbed them they ended up on a team with him. Hatsu then passed the barrier and the Door Test without much trouble.

He took part in the Crown Game with Anak and Ship. He was able to defeat most of the regulars who attacked him. However, Phonsekal Laure blasted him away with his Shinsoo. After Anak defeated Laure and made a bet with Baam, Hatsu watched the rest of the Crown Game in a moody fashion.

Hatsu was put in the Scout position for training. During the lessons, he tried to get Koon on his "friends" list. At first, they hated each other, but Baam helped to cool down the tension between them, and he became Koon's friend. He was put on Team B for the hide-and-seek test. He travelled with the Spear Bearers on the team, both of whom were very annoyed until Hatsu beat them up. He sensed Quant's ominous presence approaching by using his Shinsoo, and told the Spear Bearers to run and throw spears from a distance. Hatsu sensed that Quant was very angry, making the ranker even more dangerous. He drew his swords and prepared for the coming onslaught. When a Lighthouse revealed Quant, Hatsu blocked his attack, and began to fight him. He noticed that while Quant moves were possible for a reagular human, they had been honed to a level that was beyond human capability, and into the being that was a Ranker. He decided that he to finish the battle while Quant was still toying with him, and leapt into the shadows. He came out at high speed attacking Quant, but the Ranker simply grabbed him in midair and slammed him into the wall. However, Hatsu was able to remain consious, and grabbed Quant's hand, saying that he would not let go, and telling Parakewl and Mauchi to fire, not knowing that they had fled.

In the discussion the regulars had after Baam revealed himself as an irregular, he was the first to speak of Baam in a positive manner. When Koon acted like he was abandoning Baam for being an irregular, Hatsu became enraged and was about to attack him, calling him a coward.

In the Submerged Fish Hunt, Hatsu plays a very minor role of watching the thieves' movements. After the test, he became annoyed with Parakewl who was only concerned about whether they had passed or not. When Parakewl mentioned that Baam was dead and kept using the word dead, Hatsu threatened to kill him. He feels obligated to Baam and influences everyone to help Rachel climb to the top of the Tower.

Tower of God: Part 2 - The Return of the Prince
Hatsu is now a great and powerful swordsman in Part II, recognised throughout The Tower for his skill. He apparently once fought Rapdevil during the timeskip.

Powers and Abilities
Swordfighting Skills: Hatsu is a very good swordsman, wielding his swords fast and precisely. He is well trained, is strong physically, and can easily best multiple Regulars in a swordfight. He was even able to hold off Quant for a short time. His training also gave him an almost exceptionally powerful grip, such that he may grasp whatever he chooses without fear of losing his hold over it. His grip has proven capable of even restricting the movements of a Ranker.

Sword That Flies Higher Than Any: This sword has a blue hilt with a red tassel on it. When Hatsu throws is into the air, it will move on its own, attacking and blocking for Hatsu in midair.

Sword That Flies Lower Than Any: This sword has a red hilt with a blue tassel. This sword can emit a small but potent blast wave when Hatsu swings it hard.

Shinsoo detection: Hatsu can detect the Shinsoo of others at a long range.

Spectral Dance: A powerful sword technique Hatsu can use, strong enough to crack stone.

Trivia
As a humorous reference to old school yakuza manga or movies, Hatsu's defeated opponents were piled on top of one another, during the Crown Game.
