I never used to like the ice cream girl. I would skip all her momotalks, but damn, she's actually kind of bad
She is similar to Hifumi but Airi barely got screentime like her fellow club. So I find her cute and love for that type of ice cream silly at best. Although Airi can't compete at first since like Hifumi she barely had of those strong charmpoints that will attract a lot of people (save for few). Then devs decided to bless her.
Although she is slightly taller, having a modest soft chest and presumbly soft ass will be an eye candy if she gets a swimsuit in the future...
