Evelyne Loves to make friends so when she meet Sandoku who always has a hard time making friends well they gets along well with each other and become close friends more so with both them are hosts to Tailed Diaper beasts. Most hosts can sense the presence of one another and figured the since the two were hosts, they should play together which is why they have toys modeled after the beasts. After playing 'battle' they wanted to do a toy swap and play again.

Pampaku and Pampama are usually ok around each other, but there doing their best to tolerate each other since their hosts are happy more so with them not being happy when they see there toy lose a fight or when they toy swap. Pampaku and Pampama can't be seen by normal eyes, but tensions between the two must be strong since Artisan and Lionel are uneasy about actually seeing the dangers inside the both of them. The two critters are probably since the hosts are having the toys defeat each other and poking fun but there notthing they can do about it as Pampaku and Pampama care for their hosts in their own way and can't do any thing that may end up harming them they most like go and attack some world to make lots of diapers to cool off but this only the start of Evelyne and Sandoku doing things that will annoy them a lot.
