So To Recap,

So to recap,

Teru has a teru teru bozu motif (his name)- the weather charm paper dolls, that's why mob tells him they're the same for having a paper thin outer shell of an identity, and that's why in confession arc Teru is the one to wake mob -the paper thin outer shell of the Mob-Shigeo duality- up. It's also why he gets balded (bozu meaning bald/monk) and why there's no rain in confession arc.

Shou has a moon rabbit motif (his lackey's names + other)- fable about kindess/self-sacrifice, that's why he is shown to have similar abilities to his father as he tries constantly to reach him and is clear about his sense of responsibility to stop him from fucking up and saving him from his madness, and then in confession arc Touichirou explains how he is going to sacrifice himself in front of Shou.

Ritsu's name means law and when written differently means percentage, that's why in confession arc he reaches his first 100%. Then says he'll "confiscate" the bouquet.

Reigen's name is a pun on being blessed by the gods/gods making themselves known, and has meanings spirit and prosperous, and when written differently means heartless commoner*, that's why in confession arc he is possessed by Dimple, and is himself the one to successfully stop ???%, by confessing about a side of him he hides and dislikes because of his bad qualities.

And Dimple, well, of course, the reveal of Dimple's return is shown by none other than dimples on Reigen's cheeks.

Kageyama as a name has meaning of reflection/silhouette/shadow, in confession arc its about both Mob and Shigeo.

Mob and Shigeo are different readings of the same name*:

Mob's name is reference to being a background character, in confession arc he is pushed to the background and struggled to take back control.

Shigeo's name has meaning of thriving and husband*, in confession arc....I guess you can call it thriving.... and of course his driving force is his love for Tsubomi.

And of course, Takane Tsubomi's name means flower and her surname is a pun on "unattainable goal"*, and in confession arc she if gifted a flower, and the arc ends with a rejection.
