The 2017 romance series Seiren has arrived on Crunchyroll, offering viewers a complete 12-episode binge. The show follows high schooler Shouichi Kamita as he navigates potential romantic interests with three distinct girls: the teasing Hikari Tsuneki, the gamer Tooru Miyamae, and the childhood friend Kyouko Touno.

Produced by AXsiZ and Studio Gokumi, Seiren explores Shouichi's relationships with each girl in separate story arcs, presenting alternate realities for each potential romance. This structure is reminiscent of its predecessor, Amagami SS+.

The series delves into the anxieties of high school life alongside the complexities of young love, set against the backdrop of university entrance exams.
