Last Days of Spring

The other world is on the verge of ruin, and there’s only one way to save it… the princess needs an heir. There’s just one problem — there are no men to give it to her! That’s where I come in, whether I like it or now. I’ve been summoned to this world to save it from a horrible fate…

Shonan Saika Academy, a high-achieving all-girls school in Kanagawa Prefecture.

One day, Marin Tachibana, along with her best friends Mashiro Saotome and Kiyoka Jinguji, experiences a special day.

It begins with meeting an unusual new transfer student, Shizuku Kujyo.

A beautiful girl with a calm and dignified demeanor.

Meeting her feels like déjà vu...

While showing her around the school, they stop by an observation deck, where Marin finds a four-leaf clover.

There is a tradition at this school:

If you press a four-leaf clover found on the observation deck into your student notebook, your wish will come true.

(I want to get closer to her. To spend more time with her...)

With this wish, Marin gives Shizuku the "coincidental" four-leaf clover she found.

This act becomes a turning point, bringing Marin and Shizuku closer together with the help of Mashiro and Kiyoka. However...

"Please, stop worrying about me. I don't want to just be protected..."

"Shizuku, we're friends, right?"

A storm threatens to tear them apart.

It is deeply tied to a "secret" Shizuku is hiding and a "trauma" from Marin's past.

The story follows the growth, mutual support, and cherished memories of the four girls.

Will Marin and the others find their personal "clover" (happiness)?

Uchihama Academy has seen an increase in enrollment in recent years and as a result, a new school building will be constructed. The story takes place during the final school festival in the old school. All the club leaders decide to give it their all to make this the best school festival. Sou is a member of the notorious astronomy club, which basically solves the various issues in the student council's place.

On one day, he stays in the school late at evening because he got slightly injured by the judo club and is healing his wounds in the infirmary. Suddenly, the building shakes. Shocked, he runs up the stairs to where the shaking seems to have centered, and there he encounters a mysterious naked girl, who at first appears to know him. On the next day this girl, Yui, seeks out the astronomy club, expressing her desire to join.
