Aharen Reina - IL (Aharen-san wa Hakarenai)

Found it odd there is no IL models for Reina herself despite being the lead for the show, maybe the series doesn't have a huge following or she was forgotten? The below has her normal character, her school uniform and both her swimsuits (her initial green one she chose and the white one it switched to for some reason), you can use blue and green eyes or just one, see option tags for details:

Aharen:
aharenreina, long hair, grey hair, blunt bangs, blue eyes, green eyes, expressionless

Uniform:
Shirt, white shirt, collared shirt, jacket, cardigan

Swimsuit (White):
blunt bangs, swimsuit, bikini, white bikini, side-tie bikini bottom, frills, frilled bikini, sidelocks, alternate hairstyle, double bun, hair bun, hair flower, flat chest,

Swimsuit (Green):
Blunt bangs, bikini, green bikini, bikini skirt, frilled, frilled bikini, flat chest,

Optional:
Flat chest - not essential but creates more accurate design

blue/green eyes - can be used singular or together, blue is more accurate, green adds the green tint her eyes have but can sometimes go a bit too green, you can use both tags together for a nice realistic finish to her eyes.
