Tower of Boin

YO! You’re on the verge of kicking the bucket after some kind of accident! If things keep going like this, you’re guaranteed a one-way trip to the afterlife!

Chikan Undercover Agent Rina is a simulation game in which the heroine, an undercover police officer, fights against molesters and is subjected to various kinds of development and embarrassment!

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…

Shoko Sugimoto has opened a massage salon dedicated to healing both the mind and body, drawing on her extensive qualifications. Joining her as a trusted right-hand partner is Chuck, a massage therapist who specializes in female clients. Together, they've been preparing to provide the ultimate relaxation experience.

On the eagerly awaited opening day, their first visitors are the Otowa couple, residents of Tokyo. Though elegant in demeanor, both wear expressions tinged with worry -- hinting at a deeper reason behind their visit.

For Mari, this is her second marriage. Her first ended due to her husband's infidelity. That's why she now cherishes her life with her current husband more than anything and wants to protect it at all costs.

Their marriage, built on love, has been nothing but bliss. Mari loves her husband deeply, and each day they spend together is a source of joy. However, his demanding job has left them little time to relax and connect.

Then came a rare holiday. Seeing how exhausted her husband looked, Mari wished she could ease his fatigue, even just a little. With that in mind, she secretly arranged for a massage therapist -- a small, thoughtful surprise to help him unwind.

"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.
