Ichigo Mashimaro encore is a two-episode OVA continues onwards from the previous set of OVAs of Ichigo Mashimaro.

Fear, survival, instinct. Thrown into a foreign land with nothing but hazy memories and the knowledge of their name, they can feel only these three emotions resonating deep within their souls. A group of strangers is given no other choice than to accept the only paying job in this game-like world—the role of a soldier in the Reserve Army—and eliminate anything that threatens the peace in their new world, Grimgar. When all of the stronger candidates join together, those left behind must create a party together to survive: Manato, a charismatic leader and priest; Haruhiro, a nervous thief; Yume, a cheerful hunter; Shihoru, a shy mage; Mogzo, a kind warrior; and Ranta, a rowdy dark knight. Despite its resemblance to one, this is no game—there are no redos or respawns; it is kill or be killed. It is now up to this ragtag group of unlikely fighters to survive together in a world where life and death are separated only by a fine line. [Written by MAL Rewrite]

Even though it has been a year since the Iwatobi High School Swim Club has been created, new members have yet to join the club. Now that Haruka Nanase and Makoto Tachibana are senior students, along with their younger friends Nagisa Hazuki and Rei Ryuugazaki, they have to find a way to attract new members. If not, the club will be forced to close the following year due to a lack of membership. Meanwhile, with impending graduation, it is also time for the seniors to decide their plans for the future. Unlike their friend Rin Matsuoka, the new captain of Samezuka Academy Swim Club who is determined to fulfill his dream of being a professional swimmer, Haruka and Makoto are unsure about what career path they want to take. Further problems arise when an old friend of Rin's, Sousuke Yamazaki, comes to the city to study at Samezuka Academy; the recently scouted swimmer's arrival causes tension in the relationship among him, Rin, and Haruka.
