Beautiful female trainer
G-G-G Goon Goon Gooner!! [illujam]
- Sui
A soft and airheaded big-sister type
She’s been told she can be scary when she gets angry, so she tries not to lose her temper. Even when she does, her eyes remain half-lidded.
She cheers on gooners with a slightly pitying "you poor thing… do your best!" attitude.
In truth, she’s not very tactful.

- Mina
A high-energy gal with a chill, low-key vibe
She’s super hyped on the inside, but comes off laid-back. Yeay.
She playfully pokes fun at gooners and enjoys watching their reactions when she teases them.
Deep down, she’s actually kind.
