Kaigin

Kaigin is the friend ship between Kai Satou and Gin Ibushi from the Your Turn To Die fandom.

Your Time To Shine
In Gin's first fondness event, Gin asks Kai if he could bring one thing to a desert island, what would it be. Kai replies, "a lighter", to which Gin assumes he wants to smoke. Kai clarifies that he can use it to cook, and if Gin wanted the smell of smoke, he could make smoked meat. Gin thinks it sounds yucky, but Kai offers to make a delicious smoked meal for him later. Kai then asks what Gin would bring to a desert island, and Gin says he would bring Kai, because he seems like a useful guy. Kai is surprised by Gin's cleverness and thinks to himself that he's quite an interesting child. He remarks that Gin may have a talent for commanding people, and looks forward to what his future holds. After Gin asks, Kai says he's very close to becoming a grownup. Gin asks if he'll get taller, to which Kai says only if he eats without being picky. With that, Gin looks forward to the smoked meat.

In Gin's second fondness event, Gin asks Kai what the hardest chore is as a househusband. Kai's answer is too complicated for Gin, so he asks what would be nice to have help with, since he wants to help his mom out a lot once he gets back home. Kai is very moved by this idea of Gin's. Kai announces he will teach him all he needs to know about chores and execute "Project Make Your Mother Cry With Joy". Kai is all fired up, but Gin starts to back down, as it sounds like a lot of training to him.

In Gin's third fondness event, Gin calls Kai his "long-haired master", and in turn Kai calls Gin his disciple. Gin asks for an evaluation of his dishwashing skill, and Kai reports that his chore skills have grown dramatically. Kai is sure that his mother will be very happy when he returns home. Gin says he wants to go home soon, and is sure Kai would want to see his wife as well. Kai explains that he actually doesn't have a wife. Gin decides to help out by finding a big buff wife to go with Kai's "girly" looks, and drags Kai towards the forest, to Kai's protest and confusion.

Nankidai Twitter sketches
September 25, 2018: Kai carries Gin with a piggyback and wonders if he was so full of food that he got sleepy. Gin then stirs and digs his claws into Kai's shoulders while he grunts out "Inkya" angrily. Kai puts Gin into bed with Mew-chan to ease both Gin and Kai's shoulders.

October 28, 2018: Gin says trick or treat to Kai in an attempt to be spooky. Kai jokes that Gin is a terrifying monster and gives him some candy in exchange for sparing him.

Fanon
Kaigin wasn't a very popular friendship before Your Time To Shine since they didn't really interact in YTTD, but Gin's fondness events in Kai's Story helped fuel the pairing. Gin's outward excitability and liking to have fun goes together nicely with Kai, who is much more stoic but likes being amused as well. Some think Gin would regard Kai as something similar to a parental figure.
