It’s a shillmon, it was caught for LGPE promotion, it’s meant to be a stagnate Pokemon for the sake of being cute and cool and got its focus shorts, capture episode, moments with Kasumi and Suiren in their episode, and its out-of-the-balls scenes. The companion Pokemon aren’t going to get a ton of battles because there’s so many of them this series and most of the characters aspirations aren’t battle centric. But Nagisa is seen training with Suiren, having his hyperactive moments of personality like enjoying the hyper hot radishes that everyone disliked, participating in Suiren’s henshin scene, aggravating the Meltan. This is just about what I expected, the Eevee is her shillmon but Suiren’s ace and partner is, has and is always going to be Ashimari-Oysamari-Ashirene hence that’s why she’s gotten so much focus on the balloons, training and Z-Move stuff with her.
