Eromanga Sensei OVA

Elf Yamada, a bestselling novelist whose work is headed for an anime adaptation, hosts a celebration to thank the people who helped her reach that milestone. The mood brightens even more when her mother comes to attend—until she’s abruptly told to return home and focus on finding a suitable husband. With her feelings set on Masamune Izumi, Elf refuses to go along with the plan.

As winter settles in and the cold takes its toll, Masamune comes down with an illness. Determined to help him recover, Sagiri Izumi steps beyond the safety of her room and takes on the household chores herself, putting her care into every task as she tries to nurse her brother back to health.
