HiMERU
<section begin="HiMERU" />
 * Fellow members of Crazy:B, HiMERU doesn't have the highest opinion of Niki and is often disturbed by his and Rinne's antics due to how un-idol like they act; during Hot Limit, where Kohaku reprimands Rinne and Niki for not listening to HiMERU's explanation, HiMERU responds by saying he doesn't mind as he didn't have any expectations for them to listen anyway. He later teams up with Rinne to attack Niki for calling HiMERU a chuunibyou and implying Rinne might be influencing him. Another example is when he calls Niki in the main story and promptly hangs up on him when Niki teases him about how he's grown attached to Crazy:B.


 * HiMERU does actually care for Niki, though, and accepts Rinne's request at the end of Hot Limit to help the two of them.

Ibara Saegusa
<section begin="Ibara" />
 * Along with Rinne, Ibara was the person who convinced Niki to continue working as an idol and join Crazy:B after his former "flopped" duo idol unit with Rinne. They are idols from same agency and Niki treats Ibara like his boss because Ibara is the vice president of Cosmic Production. They are also in the circle Niki's Kitchen together; Ibara joined it to learn the many kinds of recipes that Niki knows. Ibara appears to be quite playful around him and often teases Niki whenever he has a chance to. Ibara also seems to highly respect Niki's cooking skills and is thankful that he's able to learn more from Niki.


 * As Cosmic Production's vice president, Ibara does his best to make sure Niki's needs are fulfilled. He seems to be aware of Niki's health problems too. Ibara praises his cooking skills and gives him extra privileges by allowing him to work in the ES cafeteria, Cafe Cinnamon, and even Cafe COCHI between his idol activities; this means that Niki doesn't have to worry about basic needs like ingredients to cook for his food, considering his health issues. Although Niki sometimes thinks that he is being fooled because doing idol activities exhausts him a lot and makes him need to eat more, he also doesn't want to lose the privileges that would be taken away from him if he stopped being an idol.


 * Niki has expressed worry about whether or not he can actually get along with Ibara as a coworker after learning that Ibara's favorite foods are things like supplements. This information made Niki think that Ibara has only ever eaten supplements, which would make him the complete opposite of a food enthusiast like himself. After Anzu assured him that Ibara does eat normally, Niki was quite relieved and he decided that he wants to prepare Ibara a meal someday.

Rinne Amagi
<section begin="Rinne" />
 * Rinne and Niki met when they were 17 and 14 respectively. Niki first meets Rinne on the street, approaching him out of concern for his well-being after some hesitation. During their conversation, Rinne faints. Niki then brings him back to his apartment under fear that he had died. He later elaborates that he had only done this to avoid being suspected as Rinne's potential murderer. Shortly after, Niki then faints from hunger, to which Rinne then repays him by gathering food for him.


 * Afterwards, Niki had opted to keep Rinne with him out of fear of "not wanting to be a criminal", after Rinne had put him under the impression that he had extorted the food from Niki's neighbors. As gratitude for saving his life, Niki worked hard for them to become idols for his sake. It is only much later that he finds out that Rinne had actually gone from door to door to beg for food. However, he blames himself for not knowing better, as he grew up afraid of the police.


 * During the Main Story, much like the rest of Crazy:B, Niki laments about how meeting Rinne was his turning point for the worst, showing great annoyance at Rinne's actions most of the time and complaining about him being a lazy freeloader. However, he reveals that he cares a lot about Rinne and his wellbeing, saying he'd help Rinne go wherever he wanted to during Rinne's conflict with Hiiro before the MDM. Rinne shows the same care back by entering Niki into confectionery competitions anonymously during Hot Limit so he could continue to work professionally in the kitchen without being bound by his father's failures. In an effort to display his gratitude, Niki asks if he can kiss Rinne, to which the latter replies will have to wait until after they're married (although Niki then states he has no intention of doing so).


 * Like with most others, Rinne often teases and flirts with Niki and mentions the topic of marriage as well. In Hot Limit, Rinne explains that he does this because if they were to get married and become family Niki would not have to worry about causing problems for him. The two continue to tease and quarrel with each other and serve as comic relief in Crazy:B stories, turning an eye to HiMERU's complaints about how they don't act like proper idols.
