Taichi Betsuyaku/Relationships

Tatsuya Kuruma
Betsuyaku deeply respects Kuruma, who in turn looks after his very clumsy teammate and routinely forgives him for the accidental havoc he wreaks, including the destruction of his beloved aquarium of tropical fish. It was Kuruma's patience in the face of the loss that earned him Betsuyaku's enduring loyalty. He gifted the Sniper his hat as protection, taking the idea from Yōtarō Rindō's helmet, a thought which Betsuyaku greatly appreciated. Like Murakami, Betsuyaku will not hesitate to put himself at risk to ensure Kuruma's safety no matter the circumstances. The three and Kon hang out together in their free time. Betsuyaku addresses Kuruma by his surname followed by the honorific -senpai, while Kuruma uses the Sniper's first name, without honorifics.

Kō Murakami
Betsuyaku and Murakami are teammates and friends, and on occasion hang out together with the rest of Suzunari First. Betsuyaku respects Murakami and depends on his strength. For his part, Murakami is very attached to the Sniper, whose clumsiness he finds amusing, and will do everything in his power to protect him. The two are on a first-name basis, though Betsuyaku adds the honorific -san, thus combining informality and respect, while Murakami adds no honorific.

Yuka Kon
Betsuyaku's klutziness, which his other teammates tolerate or find amusing, tends to irritate Kon, causing her to sometimes scold or even physically punish him. For these reasons, he finds her slightly intimidating. Nonetheless, the two may hang out with their teammates even outside of Border. She calls him by his first name with no honorific, presumably signifying closeness, whereas he addresses her very respectfully, appending the honorific -senpai to her surname.

Noboru Koarai
Betsuyaku is school friends with Koarai, whom he refers to by the nickname "Koala", without an honorific, seemingly connoting a rather close relationship.

Ken Satori
Betsuyaku and Satori are schoolmates, if not friends, and close enough for Satori to casually put his hand on Betsuyaku's shoulder. The Sniper of Arashiyama Squad finds Betsuyaku's antics during joint Sniper practice hilarious.

Isami Tōma
Tōma knows Betsuyaku well enough to include him in his list of targets during joint Sniper practice. During the Galopoula blitz, Tōma and Betsuyaku were seen goofing around, with the no. 1 Sniper picking up the severed head of a Dog and having it "bite" Betsuyaku.

Kei Tachikawa
While Tachikawa referring to Betsuyaku as "Taichi" in his commentary might be due to him not knowing how to read the kanji of his surname, the lack of an honorific could still suggest that the two are on friendly terms.

Sumiharu Inukai
Betsuyaku and Inukai appear to be on good terms, as in his commentary Inukai referred to the Sniper by his first name with the honorific -kun. Although the commentary caused him to burst into tears, Betsuyaku seemingly did not hold it against Inukai.

Masato Kageura
Kageura refers to Betsuyaku by his first name, without honorifics, which could imply that the two are on good terms with each other.

Hiro Kitazoe
Kitazoe refers to Betsuyaku by his first name followed by the honorific -kun, possibly implying that the two know each other.

Tetsuji Arafune
Betsuyaku originally assumed that Arafune had quit being an Attacker due to being dwarfed by Murakami's talent, but after listening to his recorded message, he learned the truth and concluded that Arafune was in reality a very kind person. Betsuyaku refers to him by his surname with the honorific -san.

Jun Arashiyama
Betsuyaku was profoundly grateful for Arashiyama's positive remarks on his unpredictability. He refers to the A-rank agent by his surname followed by the honorific -san.

Tamakoma First
Since the building of Suzunari Branch is close to that of Tamakoma Branch, Suzunari First and Tamakoma First do joint defense duty on occasion.
