Stats: 65 / 5 / 135 / 5 / 135 / 95 (440 BST)
Reasoning: While such "Minmaxed" stats can seem pretty extreme and ridiculous, we all know Naofumi by himself can't even harm a child, so he's forced to reflect stuff back to the opponent (Which he's pretty good at) with his movepool and abuse indirect means of damage.
Magic Bounce comes from being able to reflect back status techniques
Stall comes from him liking to stall out a fight if he holds the upper hand to make the opponent suffer more
Magic Guard comes from the Shield of Compassion, which leaded to him being able to use techniques such as Blutopter without having to take recoil damage whatsoever
Dark type comes from his personality to a degree (See Stall) and him already resisting darkness and soul attacks
For the movepool:
Taunt comes from him being able to bait opponents into attacking, the same also goes for Spotlight but to himself of course, Recover comes from his healing abilities, all "Protect"-family moves come from the many ways he can protect himself, Fairy Lock and Block come from him being able to trap himself and/or the opponent on this fashion, Fake Out comes from his ability to make opponents briefly flinch yet doing hardly any damage outside of that, matching quite well in flavor, Worry Seed, Rototiller, Floral Healing and Aromatheraphy come from his ability to manipulate plants on this fashion, Will-O-Wisp comes as a variation of Self Curse: Ignition as he can also use fire to burn this way, Life Dew and Wish come from ways he can heal his allies, Knock Off from his ability to remove an item from the opponent with a quick attack, and finally Curse comes as a flavorful variation of Blutopter as it's a curse-based technique, so him holding this move allows a more "natural" Pokémon feeling being around.
Custom item mechanics: Rusted Shield granting the Dauntless Shield ability after switching in is flavorful as he can copy shield abilities, and Shield of Compassion is a great item that's characteristic of him out of the benefits it holds in his canon on the same fashion as described in the picture above.
