Shun Midorikawa

Shun Midorikawa (緑川 駿 Midorikawa Shun) is a member of Kusakabe Unit.

Appearance
Shun is a young boy with short, messy light-coloured hair. When not in trigger mode, he usually wears a hoodie over a black shirt.

Personality
Yoneya likened Midorikawa's personality to a "puppy dying to show off it's talents". This was shown when he humiliated Osamu by defeating him effortlessly ten times in front of a large crowd. However, in front of Jin, he acted very silly and energetic, because of what he did to Midorikawa in the past.

History
In the past, Midorikawa was saved by Jin from the Neighbors, which is the reason why he joined Border. He joined Border a year before Yūma did.

Introduction Arc
Shun was first seen briefly in Chapter 10, greeting Jin when he returned to Border.However, he wouldn't be formally introduced until much later.

Rank Wars Arc
Shun appears again in Chapter 39, challenging Osamu, who was in his break, to a 10-round battle, to which Osamu accepted. He propositally gathered a big crowd (though he denied it was him), and then effortlessly defeated Mikumo 10 rounds in a row, only to humilliate him. Yūma, Yoneya and Yōtarō happened to arrive in the last round.

Yōtarō got angry Osamu was defeated and said he would avenge him, but Yūma challenged Shun to another 10-round battle. Shun accepted, offering his points if Yūma defeated him, but Yūma declined, instead saying he should call him "senpai" if he defeated him. Shun agreed, saying he'd call Yūma "Yūma-senpai" if he defeated him, but Yūma corrected him, saying it was his leader, Osamu, who he'd have to call senpai. They then started to battle.

Shun quickly defeated Yūma in the first round, and then again in the second round, which surprised Osamu and angered Yōtarō. Yoneya explained that there was a big experience difference between Shun and Yūma, which Osamu and Yōtarō assumed meant that Shun was more experienced than Yūma. Yoneya then explained that wasn't the case and told them to simply watch the battle. Beginning with the third round, the course of the battle changed, as Yūma started defeating Shun before he even had a chance to fight back.

The battle ended with Shun losing 8 rounds and only winning 2. After the battle, Shun apologed to Osamu, confessing he propositally attracted a crowd to humilliate him. Osamu forgave him, confessing he lost to Kazama 20 times and only drew once. Yūma then apologized to Shun, saying he propositally humilliated him, but Shun said he deserved it.

Yūichi then arrived, and Shun became energic, asking him to let him join Tamakoma Branch. Jin then asked him what about Kusakabe Unit, to which he simply said he could be part of both, which Jin denied. Yūichi then called Yūma and Osamu to the HQ, and left with them.

Powers & Abilities
Midorikawa was a prodigy, Tsutsumi noted that he only took 4 seconds in defeating the Neighbor Simulation at his first try. He is also very powerful for his age, as he was able to defeat Osamu all 10 times they battled nearly effortlessly. Even Yūma admitted he couldn't have won if his mentor hadn't trained him as she did. He even noted that Midorikawa switched tactics every time he battled to fool opponents. Yūma likened his fighting style to an animal, saying it was almost erratic.

Trigger
Midorikawa is an attacker. While he implied that he could use more than one kind of Trigger, he mainly uses Scorpion.
