Sisterly Bliss ~Don't Let Mom Find Out~

"The human heart is but a vessel for pain."

That's what someone once whispered―a voice laced with loneliness, whispering directly into the soul. It's an indescribable sadness, a love just beginning to bloom. It becomes an invisible pain that pierces the heart. And that's what makes up life: a cyclical series of highs and lows.

Tachibana Sai was born without the ability to feel pain in his heart. He spends his days eliminating any seeds of malice that sneak up on his sister, the one person he treasures, without drawing attention to himself.

Sick of the never-ending monotony he lives through, he chances upon a meeting with Benio Matsuri, a young girl whose aloof demeanor resembles that of a beautifully crafted doll.

For the first time in his life, he encounters a heart-piercing sensation―that of falling in love.

On the edge between day and night, in a twilight world where the dead and living mingle, stands an apartment building called Maison sans Nom, which is home to a group of boys and girls.

A ruthless boy who knows no pain in his heart.
A lonely girl without any friends.
A friendly girl who struggles to make connections.
A prickly, ambitious girl who is keen to be of help.
A boy who loves his own cute self above anything else.
A mess of a woman who tries to solve everything through brute force.
And a boy with a tender heart who knows no pain in his body.

This ill-assorted group of residents, hands stained with blood from battling the supernatural Maledicts, shall encounter the hearts they never knew and begin nurturing their souls.

The human heart is but a vessel for pain.

To protect this pain akin to love... To gently break the world apart, piece by piece... Even if it means abandoning humanity. That's why the heart is but a vessel for pain.

For life blazes brilliantly, while the heart goes around in an endless cycle.

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.

At the Saint Michael Girls' School... festivities erupted among the girls of the annex. The reason for their celebration is the Best Couples poll being held at the main campus. The students at the annex, who look up to the girls from the main campus, decided, "Let's have our own Best Couples!"
...It was always inevitable.
And so, the fairest and most intimate couples were nominated...

The first couple is a pair of childhood friends, Misawa Nagisa and Takahata Rina. The second couple is a pair of twin sisters, Kimishima Ai and her younger sister Aya. And finally... The transfer student who saw this whole thing as no concern of hers, Onohara Hazuki, is shocked to hear that she too, was chosen to be among the Best Couples.

Moreover, her partner is the sheltered young debutante, Suoh Manami. Actually, Hazuki has secretly been crushing on the impeccable Manami... But the truth is, they're far from a couple, and while their classmates may cheer them on, it's all in vain.

But then... Hazuki works up all her courage to ask Manami to become a "Best Couple" with her, and...

Janieve High is your average all-girl high school. The only thing that makes it stand out is that it is the first school in the country to try out the bridge year initiative. Claudia Flaurance, great-granddaughter of the school’s founder, takes this opportunity to be part of the first wave of students for this optional seventh year of high school. Now that she finds herself alone and without friends in a class full of girls who have known each other for years, her new life at her ancestral school can begin.

Two other girls, Gabriella and Michelle, won’t let Claudia be friendless for long though. Together they try to find a school club to join to solidify their friendship.

But wouldn’t starting your very own club be the better option? And with that Claudia is not only the new girl, but also the president of the brand new book club.

This new book club has something to hide though. Girl-girl romance books are the only books on the menu! Now renamed to the yuri club, this club might just be what Claudia needs to get to the bottom of Gabriella’s and Michelle’s past. And if they can secretly help other girls at the school confess their love to each other, that’s even better! That is what the yuri club is all about.

Can Claudia find her place at Janieve High? Can the school help her understand the mysterious mood sensing power she’s been struggling with since childhood? And most important… Can love conquer all? Or will Janieve High’s anti-relationship rule be the end of the yuri club?
