–Shooting bullets which would miss, huh? My pride as a sniper wouldn't allow that. 'It can't be helped that he sees our bullets coming.' It's 'cause you think like that you'll always be no. 2., Isami Tōma to Tōru Narasaka in Kei Tachikawa.
Isami Tōma (当真 勇 Tōma Isami? ) is a character in the manga and anime series World Trigger. He is an A-Rank agent from Fuyushima Unit and the No. 1 Sniper in Border. Due to his actions, he is a minor antagonist of the Black Trigger Retrieval Arc, but later turns into a supporting character.
Tōma is a tall individual, with black hair slicked back, forming a small pompadour on his head.
Tōma can be very arrogant, downplaying anyone who he judges weak, as shown when he mocked Narasaka's line of thinking, saying that was what made him no. 2 Sniper. Despite that, he's also very friendly, and recognizes a strong enemy. He likes setting personal goals and creating difficulties in its pursuit. In general, he has a very playful, carefree attitude.
- Yūichi Jin: Tōma seems to respect Jin.
- Yuzuru Ema: They seem to have a good relationship, although Ema dislikes when Tōma says he's Ema's mentor.
- Izuho Natsume: Tōma befriends Izuho after her cat lands on his head. He gives her Sniper tips, effectively becoming her mentor.
- (To Narasaka) "Shooting bullets which would miss, huh? My pride as a sniper wouldn't allow that. 'It can't be helped that he sees our bullets coming.' It's 'cause you think like that you'll always be no. 2."
