Esther

The young Esther was assigned to the front line to fight against the infected after graduation. She wasn’t just an excellent fighter but also an outstanding instructor who has trained numberless brave fighters these years. Recently, Esther’s been appointed as director of Student Affairs due to the heating up war against the infected.

It’s said that she was a “bosozoku”, known as “daughter of the ghosts killer”. She is usually kind and gentle, but she is a “devil instructor” in the training class. Most of the girls at the Campus are sfraid of her training class. Unexpectedly, she hasn’t been getting along well with the president of the Student Council.

She always hears rumors about Senpai after becoming a teacher and starts to get interested in Senpai.
