HiMERU

 * Fellow members of Crazy:B; HiMERU gets along with Kohaku the best. As the more reserved (and arguably, sane) members of Crazy:B, they're frequently paired as a duo, and Kohaku mentions he considers HiMERU his first friend from when he first arrived in the city.


 * HiMERU becomes slightly cautious of Kohaku after Kohaku implies he's at least vaguely aware of his secret in one of HiMERU's idol stories, but generally speaking they are well-acquainted.



Ibara Saegusa
<section begin="Ibara" />
 * Kohaku is one of the members of Crazy:B who worked with Ibara during the Crazy:B rampage during the beginning of the !! Main Story. It was said that Ibara holds a secret of Kohaku's as a key of trust. Ibara stated that, aside from Niki, all of Crazy:B's members were bound to meet a fate worse than death if their contract with Cosmic Production was to be terminated. There weren't many signs of interactions between Kohaku and Ibara until A Dark Night's Passing, where Ibara hired Kohaku to investigate GFK in order to break out of a problem Crazy:B had. It's also been implied that they had another deal that has yet to be revealed.


 * Despite respecting Ibara's position as vice president of the idol agency he belongs to, Kohaku doesn't hesitate to speak bluntly to him and even throw snarky comments his way if he deems it necessary. Although he appears to despise Ibara's "evil acts" and often reminds him not to get ahead of himself, Kohaku did acknowledge Ibara’s tactical moves to handle the Cosmic Production idols' problem in Antique Legend.

Jun Sazanami
<section begin="Jun" />


 * Jun and Kohaku are roommates in Starmony Dorm. Both Crazy:B and Eden belong to CosPro, so they express support to each other as members of the same agency. Jun calls Kohaku "Sakura-kun" because of the cherry blossom character '桜' in Kohaku's name, which Kohaku seems to dislike. However, Kohaku just grumbles quietly about it every time it happens, which is probably why Jun continues to do it.
 * Kohaku reached out to Jun in Secret Service to find out what Madara was up to in Shikoku. When Kohaku expressed his frustration at the 'no travel' restriction that prevented him from finding Madara himself lest he get Crazy:B into trouble, Jun said that he thought Kohaku was a distant character in the beginning who had no one to cherish, and was happy that Kohaku had now found so many friends that are dear to him.

Souma Kanzaki
<section begin="Souma" />
 * In A Dark Night's Passing, Souma happened to overhear Madara's and Kohaku's plans, and gave chase when they tried to run for it. Due to Crazy:B's reputation, he thought that Kohaku was trying to kidnap Madara, even though Madara was the one carrying Kohaku on his shoulders. After the misunderstanding was cleared, Kohaku apologised to Souma over the damage done to AKATSUKI during MDM, but Souma brushed it off, saying no real harm had been done.


 * Kohaku mentioned that the Kanzakis and Suous (+ Oukawas) had clashed in the past, both being families with a long history.

Madara Mikejima
<section begin="Madara" />
 * In A Dark Night's Passing, Madara and Kohaku unite to form the duo unit Double Face.


 * Kohaku and Madara are shown to be comfortable speaking to one another, with Kohaku noting that Madara is so easy to talk to that he began "chatting" while ignoring important subject matter.


 * In Learning from the Past, Madara alludes to Kohaku several times as a member of Double Face without directly mentioning his name, referring to him as "that child". He states that Kohaku had been helping him take care of tasks assigned to him by Rei off-screen.


 * Dialogue between Madara and the other characters surrounding Double Face seem to imply that they had been working together for some time by the time the event Learning from the Past／Succession Match takes place. However, Madara still claims to view Kohaku as a business partner whose interests align with his at times and that they aren't that familiar with each other. Rei Sakuma then states that he was also like that at the beginning, but that they'll eventually become inseparably attached to each other.


 * At the end of A Dark Night's Passing, despite their mission to take down GFK being completed, Madara informs Kohaku that Anzu will continue producing them together as Double Face, as solo units are not permitted to perform on the renewed show Marble Cast. Kohaku initially took an issue with this due to believing that working with Crazy:B was already a handful, but doesn't appear to mind by the event's end.

Rinne Amagi
<section begin="Rinne" />
 * Fellow members of Crazy:B, Rinne often teases Kohaku, calling him 'Kohaku-chan' and treating him like a child on multiple instances much to Kohaku's chagrin; they often don't see eye-to-eye, leading to squabbles. Rinne does concern himself over Kohaku, though, and does his best to nudge Kohaku in the right direction as shown in the Honey Bee scout story, where he purposefully challenges Kohaku to find a job for Crazy:B as to help him build self-confidence.
