Blend-S(2013)

Blend S

High schooler Maika Sakuranomiya can't seem to land a part-time job, so when an opportunity comes knocking, she's up for anything. Waitressing at a cute café—sounds perfect! The manager demands that each waitress adopt a quirk in their service? Not a problem. Maika's ready to act flirty, or hot-and-cold, or like a little sister, or…sadistic?! Oh. That might be a tough one for our cheery and caring heroine! The original manga behind the popular anime!
