Yellow Gate!

Gin takes on an escort assignment to settle the debt his parents left behind. The job is arranged by the Tokugawa Group's bill collectors, and his client is Hikari, a student at Tokugawa Private Academy. Alongside two other escorts, Suke and Kaku, Gin uses skills from his past part-time work to ensure her safety. As the mission progresses, it becomes apparent that Hikari may be concealing something.
