Kaikanna

Kaikanna is the friend ship between Kai Satou and Kanna Kizuchi from the Your Turn To Die fandom.

Your Turn To Die
Following Mishima's death, when Miley is taunting Kanna about killing her sister in the First Trial, Kai smacks Miley with his frying pan to make her stop.

Your Time To Shine
In Kanna's first fondness event, Kanna suddenly runs into Kai to see if his chest is flat, and therefore a man. She finds that it's true, and with embarrassment, explains that she wanted to find out because she couldn't believe someone so pretty was a man. Kai doesn't mind at all, but warns her that by tackling him like that, he might accidentally counter-attack by reflex. Kanna asks why he has a habit of that, and Kai decides to say it's a counter-attack of affection instead of the more serious truth. Kanna is glad to hear it and tells Kai to go ahead. Kai lightly hugs her and she thinks he really is like a mom. When Kai reminds her that he's a man, Kanna realizes what she just said, asks him not to tell anyone, and runs off embarrassed.

In Kanna's second fondness event, Kanna shows Kai an item identical to the bucket on her head and asks him what he thinks. If Kai says it's a bucket, she giggles that he didn't have to think so hard about it because it's obvious. If he says it's a hat, she gets confused, since it's apparently most definitely not one. Kai then points out what she's wearing on her head, which she refers to as her hat. Kai tries and fails to politely ask what the difference is between her hat and the bucket. Kanna assumes that Kai wants to wear her hat, but is discouraged by the fact that they won't be able to get one like it on the island. Kai asks Kanna to close her eyes, and puts the bucket on his head in order to prove that the two are basically the same. However, Kanna just laughs when she sees it, thinking Kai is funny for putting a bucket on his head.

In Kanna's third fondness event, Kanna is about to call Kai "mom", and he catches this. She tries to pass it off as if she was going to say "my Kai", as you would say "my lady" to show respect, but when Kai calls her "my miss Kanna", she thinks it's weird. Realizing what happened, she explains that she actually was going to call him "mom". Kai asks if Kanna likes her mother, and hearing that she does, Kai says he's glad to be mistakenly called that. Kanna shares a little more about what her mom is like, and then gets sad because she misses her. To comfort her, Kai hugs her tightly. He cheers her up, and promises to protect her while they're on the island as her "my Kai". Kanna gets embarrassed and runs off once again.

Official 4-koma comics
S2 #12: Kanna hugs Kai and excitedly asks him if any of the guys in the Death Game are his type. Kai worries that Kanna must think he's a woman, hence her question, but if he corrects her, then she might stop trusting him. Kanna giggles, and Kai is surprised by the fact that it seems she already knows.

Fanon
Kaikanna isn't an incredibly popular friendship, as they didn't interact at all in YTTD. Their wholesome interactions in Kai's Story, however, helped fuel the friendship and show that Kai would be a good and reliable adult figure to Kanna. Since Kanna wanted to call Kai "mom", and when Kai first hugged Kanna he saw it like he was pampering a niece, the two are often seen as having a family-like relationship.

Additionally, Kanna's love of sweets could indicate that she'd be enthusiastic about cooking/baking, and Kai could teach her how to make things.
