Shortly after Eijun Sawamura entered Seido High School. During a school-wide assembly, a transfer student was introduced.
"This is a transfer student who will be attending this school starting today. I'll have them give a brief self-introduction."
The eyes of everyone in the gym gathered toward the stage.
