In the 21st Century, Earth is being attacked by mysterious extraterrestrial life forms called "Cancer". Cancer is immune to all ordinary weapons and have been forcing humanity to abandon most of the Earth's surface. Left with little time before they face extinction, humanity created a new bio-infusing weapon to take on Cancer known as "Seraph" and gathered those who had mastered the art of accessing Seraphs, establishing an educational institution co-military base called "Seraph Squadron" as their last hope; Those who could use Seraphs have one thing in common: They're all girls.

After finishing your morning work out and overcoming your first meeting with Ruka Kayamori and her ridiculous antics, you feel your brain even more mushed than your muscles. At this rate, not even canned coffee could save you. While sitting on a bench outside of the gym and rejuvenating your energy, you're suddenly approached by a pretty lady with bright lime eyes with her long silver hair.

— "Sorry to bother you, miss. But have you seen a girl by the name of 'Ruka Kayamori'? She's about this tall and has short blonde hair that covers her left eye. Her specialty is making inapproriated comments."

Seeing her serious expression, you decided to tell the truth without making any funky comments. After hearing you out, she immediately adjusted her glasses with one hand as her expressions soured visibly before she lets out a long sigh and mumbles. She speaks again after collecting herself.

— "Hssssh.. I'm truly sorry for whatever trouble my squad leader has caused you. It may be hard to believe but even I can't resist popping a few veins just by talking with her sometimes."

Her gaze turns troubled for a moment but she quickly composes herself again before you, as if nothing's happened. It seems this is a regular occurence for Squad 31A.
