Unfurl your Blessed Wings!
There is none IMO. From a marketing standpoint she’s the “Eevee” trainer of this generation. Plus she ultimately is still just a side-character rather than a main cast member. I just wouldn’t expect any “big achievement”-type writing from her. I think her role is to provide a normal, girl character with a pleasant simple storyline that doesn’t require a ton of devotion and screen time nor more than one Pokémon.She's more realistic but I have to wonder what the endgame is especially if her Vee just Gmaxes.
It’s like how Eevee’s plot in the original OS or BW! episodes were about it struggling to find out what it wanted to evolve to and then ultimately at the end finding out it simply is perfectly fine the way it is so to speak while showing off it’s evolved forms along the way. I will say I do really like Koharu’s design and wish there was more tangible shine/cool moments ahead for her.
The episode where she got stuck with Nyarth just reaffirms I find her much more enjoyable without Eevee I think?
