Itano and Shirogasaki
Itano and Shirogasaki are two young students attending the same class as Raku and the gang. Although appearing only once so far, Itano appeared in the series as a fat and round kid while Shiro is shown to be the shorter-haired skinnier kid of the duo. They were the first ones beside Kosaki to discover Raku and Chitoge's supposedly date around the city, and were also responsible for spreading the news in their class of what they saw. Hilarity then ensues when the whole class thought that the two were a couple; causing distress upon Raku, Chitoge, as well as Kosaki.
Shu Maiko's middle-aged distant uncle is a blacksmith who takes up the role of fixing Raku's pendant, after Chitoge's key broke off and got stuck in its keyhole when she and Raku tried to open it. Like his nephew, Shu's uncle is a pervert who buys and prizes his nephew's voyeur photographs of school girls from his class. In the end however, he fails to fix Raku's pendant, knowing that it might break if further touched upon.
Shu's Mother is an unnamed female character and said mother of Shu Maiko. She has no physical appearance in the series so far, but she was prominently mentioned once by Raku during a flashback about his and Shu's childhood. Her character has somewhat been an important plot element during the "Shu's Crush" story arc, revealing that one time she got ill when the two boys were still little children. Raku remembered very well that even so, Shu still kept a happy facade even in the face of this crisis. What Shu didn't know however, was that Raku has always known that he was just pretending, and he revealed that Shu was actually harboring sadness during that time. Back in the present day, Raku used this memory to deduce that Shu is again masquerading a fake smile after getting heartbroken when his crush; Kyoko-sensei, revealed that she will be marrying soon before retiring from the school. Raku then rallies Shu up to finally confess his feelings to her rather than keeping it to himself, and the latter happily obliged Raku to kick him in the back in order to get him to confess.

He constantly annoyed Ruri with his upbeat and perverted personality, which included collecting embarrassing photos of Ruri when she was a child. He considered Ruri as his own pride and joy, but worried about her life in the city, fearing that she may not have any friends because of her serious and deadpan personality. He later revealed to Ruri that his only dream before dying was to witness her marriage with the man she truly loves.After hearing news that he may not have that much time to live, Ruri was forced to pay him a visit, and was even coerced to invite Raku to pretend as his boyfriend when the household mistook him as so. At first, Ruri thought that the apparent news was just another usual excuse her grandfather's been using again, to make her spend some time with him. When they arrived at Yoshizou's house, the old man became acquainted with Shu Maiko after the latter sold his rare photos of Ruri to him (Ruri even remembered that Shu reminds her a lot of Yoshizou). Like what she does with Shu, Ruri isn't shy about in hurting the old man in times when he shows his perverted nature. Still, the two has shown a very strong bond with each other during the visit, and Ruri even brought Yoshizou his favorite eclairs, as well as playing video games with him. However, a week after Ruri, Raku and Shu finally left the house, news came to them that Yoshizou died soon after, and a tearful Ruri regretted not smiling with him when he was still alive.

To waste some time, Raku and Kosaki decided to visit a locksmith stationed in the mall in an effort to again get Raku's pendant fixed.

Panicking, Raku and Chitoge snuggled themselves under their futon to hide, creating one embarrassing but lovely scene.
