Tsukishima kei

Tetsurō Kuroo and Kōtarō Bokuto: During the Summer Training Camp Arc, Tsukishima trained with both Kuroo and Bokuto upon request. In their training matches, Tsukishima received advice from both of them while also paying close attention to their movements. The two are primarily responsible for Tsukishima's improvement; Kuroo taught Tsukishima the proper way to block successfully and Bokuto taught Tsukishima "that moment", which Tsukishima used as motivation in the match between Shiratorizawa and Karasuno. During the Summer Training Camp, Bokuto and Kuroo began calling Tsukishima by his nickname 'Tsukki', much to his annoyance.

As for his relationships with his teammates, they vary, though he holds some members in contempt. To begin with, he looked down on both Kageyama and Hinata, the former for his infamous reputation as the bossy king of the court (even calling him by that nickname just to mock him) and the latter for his short stature and hot-blooded demeanor. This disdain also extends to his second-year upperclassmen Tanaka and Nishinoya, who are also hot-blooded (a trait he found irritating). He did not train with Karasuno during his time at the club. However, he did respect his third-year upperclassmen Daichi, Sugawara, and Asahi, but probably because they were more level-headed. Nevertheless, before being reprimanded by Yamaguchi for not giving his best, he felt the team's efforts to improve were futile and thought they would lose anyway. Unlike most of his teammates, Tsukishima isn't particularly attracted to Kiyoko and hasn't interacted with her much so far.

Tsukishima and Kageyama didn't get along, mainly because they got off on the wrong foot at first. Tsukishima used Kageyama's past as a terrible teammate to insult the latter often, and Kageyama would often yell at each other; their fighting almost led to violence at one point. Tsukishima was surprised by Kageyama's change at first, especially when Kageyama asked him about his preferred pitch type. Since So, the two now see each other as teammates and work together during matches, able to perform time difference attacks as well as work together as part of Karasuno's "total defense."

Tsukishima initially treated Hinata in a rather antagonistic way. Hinata reprimands Tsukki Tsukishima expressed his dislike for Hinata's hot-blooded nature towards volleyball despite his lack of height, even going so far as to attempt to crush Hinata's spirit during their 3-on-3 match at the beginning of the series. It was later revealed that this stemmed from his brother's volleyball history at Karasuno. Tsukishima also initially considered himself inferior to Hinata in terms of skill, as noted by some of his teammates and Kuroo. After discovering his own love for the sport, Tsukishima has developed a slightly more competitive rivalry with Hinata, as they are both middle blockers.

Tsukishima has an older brother named Akiteru, who was a member of Karasuno's volleyball club at the same time as the Little Giant. Akiteru is both the reason for Tsukishima's interest in volleyball and his current attitude towards it—that is, the idea that one shouldn't put too much effort into club activities because in the end, one will only get hurt. Tsukishima used to adore his brother and often asked him to teach him volleyball skills as soon as Akiteru got home. However, their relationship was destroyed when Akiteru lied to Tsukishima about being an ace on his team, only for Tsukishima to find him in the stands during a match. Since then, Tsukishima would avoid talking to Akiteru, and whenever Akiteru came home from university, Tsukishima would lock himself in his room until dinner time. After the summer camp in Tokyo, the brothers finally talked about their past and reconciled based on that. They are now slowly rebuilding their relationship.

The person closest to Tsukkishima, who calls him by his nickname Tsukki. When they were younger, Tsukishima rescued Yamaguchi from bullies by calling them pathetic. Because of this, Yamaguchi later bonded with Tsukishima, yearning to be as cool as him. Yamaguchi and Tsukishima are rarely seen apart. They are both often portrayed making fun of others together. However, as time passed, their relationship began to drift apart in terms of training. While Yamaguchi persevered in working on his jump float serve, Tsukishima exerted no more effort than necessary. This worried Yamaguchi and some of the other members, but they initially said nothing. Later, in the Summer Training Camp arc, Tsukishima still refused to put any effort into his training because he didn't see why he should. His behavior enraged Yamaguchi, who for the first time yelled at Tsukishima, asking him what more motivation he needed than pride. This changed Tsukishima's way of thinking and impressed him; he even called Yamaguchi "great" for the first time. Tsukishima began to work harder, and their relationship returned to normal after this event. Yamaguchi currently works for a company that also supports the Sendai Frogs, and whenever he can, he goes to their games with the excuse of representing his company.

Tsukishima is always somewhat distant, although he doesn't bother her as much with his jokes and sarcastic replies as he does with the others.

Judging, analytical, quite serious and arrogant, always makes fun of everyone and everything seems pathetic to him, he is quite introverted and reserved with people he doesn't know and doesn't really like to talk about his personal life, quite jealous
