Daichi Tsutsumi/Relationships

Suwa Squad
The members of Suwa Squad have a good relationship and hang out together outside of Border duty. Despite his penchant for gambling in battle, Tsutsumi trusts Kōtarō Suwa, whom he calls by surname, presumably out of respect, even though they speak casually to each other otherwise. Tsutsumi similarly addresses Rui Osano by her surname, whereas she uses a nickname for him, and calls Hisato Sasamori by his first name.

Nozomi Kako
Tsutsumi and Kako are on good terms. He addresses her by surname followed by the diminutive suffix -chan. He often volunteers to try out, her experimental fried rice dishes out of curiosity, although he has gotten sick on two occasions.

Reiji Kizaki
Tsutsumi appears to hold the Perfect All-Rounder in high esteem in terms of sniping and mentoring skills. Like the rest of his Squad he refers to Kizaki by his first name, which suggests familiarity.

Tamakoma Second
Tsutsumi is very impressed with the three original fighters of Tamakoma Second. Although he admires Yūma's skill and speed, Osamu's tie against Sōya Kazama left an even more lasting impression on Tsutsumi, who has taken to observing Osamu with interest. He refers to the latter by the nickname "Four-Eyes".
