Assuming that you treat Daima as canon to Super. what is your personal head-canon as to how Shin and Kibito ended up fused into Kibito Kai again?
Here's my own version:
- Shin and Old Kai end up getting into a heated argument, based around Old Kai accusing Shin and Kibito of hiding his "special" magazines. As such, Shin and Kibito decide to take a trip around some of the planets in the 'Mortal' Realm to get away from the Sacred World of the Kais for a while (in order to let Old Kai "blow off some steam").
- After visiting several planets, they eventually end up in the 'Oasis' on Planet Rudeeze, where they come under attack from a group of Sandipedes. Although Kibito and Shin are able to repel their attackers, they are hit with a sand blast from one larger Sandipede that blasts off their Potara earrings.
- While Kibito (half-blinded by Scorpulon's sand blast) complains about how he hates sand - due to it been "coarse and rough and getting everywhere" - Shin tells him to stop acting like a whiny teenager and to find their Potaras.
(A little reference to Star Wars as Toriyama was a fan).
- Unfortunately, while both Shin and Kibito find a Potara, Kibito - still half-blinded by the sand and impatiently wanting to get off Rudeeze - doesn't bother to check which one it is before attaching it to his ear; the opposite ear to the one Shin attached the Potara he found to.
As such, the Potara fusion initiates before either can stop it; resulting in Shin and Kibito become Kibito Kai once again. Although they later go to Earth to ask Buu to separate them again, Buu refuses - childishly stating that he did it once and doesn't want to do it again.
- When they return to the Sacred World of the Kais, Old Kai is in a much better mood; revealing that he simply moved his magazines while doing some spring cleaning and forgot that he moved them. When he asks why Shin and Kibito are fused again, the fused Kais - with a defeated tone to their voice - simply replies with "Don't ask".
As such, they're stuck as Kibito Kai until after the "God of Destruction" Saga, when they later gather the Namekian Dragon Balls - erroneously believing that Champa wanted them - and using a wish on the Dragon Balls to be separated back into Shin and Kibito again.
However, what's your personal head-canon as to how Shin and Kibito became Kibito Kai again between the events of Daima and Super?
Curious to see what you guys think.
