Tatsumi Kazehaya/Relationships

Aira Shiratori




Kohaku Oukawa




Hajime Shino




Hiiro Amagi

 * As fellow members of ALKALOID, Amagi Hiiro and Kazehaya Tatsumi are on good terms.
 * They are similar, because both do not know much information about the outside world, due to their little knowledge about it. That leads to mispronunciations of everyday objects, like "download," which Tatsumi pronounces as "down rood," or "smartphone," which Tatsumi pronounces as "sumart foon."
 * When Hiiro first sees Tatsumi, he assumes that Tatsumi doesn't have any weak spots, since he has a calm demeanor. He then goes to believe that Tatsumi is a martial arts master because of his assumptions.
 * Hiiro stared at Tatsumi's face for too long, that Tatsumi asks Hiiro if there is anything wrong with it. Hiiro then says that it is "uncloudy and well-proportioned."



Mitsuru Tenma




Tomoya Mashiro

 * Tatsumi has helped Tomoya with his sleeping issues in Weekend's Confession Booth.

HiMERU
<section begin="HiMERU" />
 * HiMERU and Tatsumi have a long history together as Reimei Academy's (former) most popular idols.


 * The former HiMERU was well-befriended with Tatsumi, despite their status as 'rivals' as renown idols on top of both being special students. They first talked at a party, wherein HiMERU accidentally revealed the name 'Kaname Tojou' to him. The two were close, and HiMERU held Tatsumi in high-regard (the current HiMERU goes as far to say he was his number one devotee), once describing a vision of the "strongest Tatsumi Kazehaya" to him; he pictured him as an angel with three pairs of glistening wings (making for a total of six), with a gaze that'd kill any enemy who'd look at him. This Tatsumi would therefore keep his eyes closed, with a mole growing under his eye for every of his perished enemies. HiMERU was also comfortable enough with Tatsumi to talk in first person around him, and talked about feeling suffocated by 'HiMERU' with him, something that the current HiMERU does not remember.


 * On the contrary, the current HiMERU has an overwhelmingly negative opinion on Tatsumi; he stays polite towards him, but prefers to avoid Tatsumi whenever he can and spy on him from a distance instead. His hate for Tatsumi is strong enough to offer Tatsumi a particularly disgusting drink in one of his stories, hoping it'll break Tatsumi's usual composure (and ends absolutely horrified at how this turns against him later). HiMERU often calls him 'saint bastard' and has a tendency to chant Tatsumi's full name during his inner monologues, criticizing his past actions and loathing him for how this ended up influencing the former HiMERU, who ended up hospitalized during the revolution. During a heart-to-heart in the later chapters of the main story, HiMERU even states he'd be willing to kill Tatsumi to make the sorrows disappear.


 * The current HiMERU does recognize Tatsumi did not have malicious intents during the revolution, and shows sympathy for the way Tatsumi was treated in return, but remains spiteful for hurting the former HiMERU the way he did.

Jun Sazanami
<section begin="Jun" />
 * Jun and Tatsumi both share a class in Reimei Academy (3-S). However, when Jun approaches Tatsumi in the staff cafeteria, Jun comments that he hasn't seen him in school in forever—likely due to his hospitalization. Jun has expressed that he always admired the Legendary Tatsumi Kazehaya, and has always idolized him since his Non-Special Student days even until now. Because of that, Jun shows great respect towards Tatsumi, and even offers to help Alkaloid back when they were struggling at MDM. However, Tatsumi doesn't seem to have known Jun prior to their meeting at Ensemble Square.

Mayoi Ayase
<section begin="Mayoi" />
 * Fellow members of ALKALOID. Mayoi and Tatsumi grow fairly close throughout the main story, though Mayoi tends to be bad with Tatsumi's frequent displays of affection and how "pure" he seems to be. Tatsumi refers to himself as the "father" of ALKALOID, and refers to Mayoi as the "mother"; this is something Mayoi denies at first but accepts later on. The two often tend to depend on each other, whether it be Tatsumi carrying Mayoi when he feels sick or Mayoi giving Tatsumi a piggyback ride when his legs hurt or he is tired.

<section end="Mayoi" />

Ritsu Sakuma
<section begin="Ritsu" />
 * Tatsumi referred to Ritsu as "Satan" the first time they met due to sensing evil in him, which is likely due to Ritsu's relation to the Sakuma Clan and their vampiric constitution.

Hiyori Tomoe
<section begin="Hiyori" />
 * It is unknown how Tatsumi and Hiyori have met in the past, but in Tatsumi's idol story with Jun and Hiyori, Tatsumi says to Hiyori "After being unable to speak with you for so long, it's a delight to see you once more."
