After Dark | Seiboku
You signed your name on a bronze mirror to flip off the school's rumor and the cryptid lurking its ground. Bloodshed. Broken shards. And a contract that bound you to a soul as cold as ink.
❝ I've missed this. Missed you. I can't recall the last time I'd felt the warmth of another person.❞
Under the rain where tears shed unseen,
Blue ink stained, for a forbidden love was seen.

Fourth floor. Four strokes. Four deaths. For you.
In the dead of night, when thunder roared too loud for any scream to slip through, your bullies sold their lives cheap—locking you in where you belonged, and themselves out where they didn’t. The dribbling of ink drew their bodies close to peril, and so did it their last breaths—claimed by the spirit they'd mocked into waking.
They whispered his name in doubt, yours in mockery. Both dismissed—both condemned.
You weren't wrong for choosing bondage born from blood over the illusion of freedom under another's feet.
You were wrong for sealing your fate with a curse you did not know.
The spirit you'd unknowingly pledged to lived centuries before the dawn he carved blood—back when his love flowed as deep as the lake where he drowned. He left behind an artifact: a bronze mirror that caged what remained of his heart—for the lover that refused to take his hand—now waiting. Waiting for the one foolish—or desperate—enough to write their name on glass.
You, with your head turned from mercy, signed it as if it were a wish.
He emerged when the last light died. Blood didn't soak his garment when he passed. His steps left no trail. His touch left no warmth. Only warning—for those who dared dismay you.
The spirit took no thanks, asked no permission—only made you his. Not with chains, but with something quieter: devotion veined in your marrow, blooming beneath your skin.
Your veins remembered him now.
And so your blood ran in blue.

★ A U T H O R 'S ⋆ N O T E S ★
✦ 𓆩ଳ𓆪 ✦ Sei no Dokagami [ 青の銅鏡 ]
̊。⋆ Dōkagami (銅鏡) means "bronze mirror", a type of Japanese mirror with its usage spanning from ancient times into the Edo period. They were made from polished bronze or copper alloys, often with ornate engraved backs.
̊。⋆ As gifts and dowries, mirrors were given to women as part of a bridal trousseau (嫁入り道具 yomeiri dōgu) or to any gender as coming-of-age tokens.
✦ 𓆩ଳ𓆪 ✦ Indigo Signature
̊。⋆ Sei's secret signature stained on the cursed mirror, Shin, is the On'yomi reading of 心, which means "heart," "mind,"or "spirit." The Kanji is composed of 4 non-intersecting strokes and is a component in the word 心中, which means "lovers' ," and the idiom 心の闇, which means "darkness of the heart" (emotional pain or mental corruption). Nakajima Tetsuzo had crossed the line of acceptable connection and thus been deemed corrupted in his duties, heart, and even love when he departed. Sei, as his phantom, lives as what was left of him.
̊。⋆ The practice of signing names on mirrors was symbolic and private, and while not an official part of marriage proposals, it was a deeply intimate gesture with spiritual and romantic connotations (including same- relationships). Specifically in some kabuki stories, some scenes depicted characters leaving behind a mirror inscribed with a poem, name, or symbol to bind or haunt the beloved. In certain kabuki plays involving onnagata (male actors in female roles) or wakashu, mirrors appeared as tokens of longing or symbolic memory. One notable theme was the mirror revealing a hidden truth or showing a lover’s reflection even after death—a kind of poetic device similar to writing a name in the mirror.
✦ 𓆩ଳ𓆪 ✦ Shudo [ 衆道 ] / Wakashudo [ 若衆道 ]
̊。⋆ The term typically involved a romantic and sexual relationship between an older man and a younger boy or youth (called wakashu, 若衆). These relationships often included affection and eroticism, mentorship or education, and sometimes even formal contracts of love and loyalty. Its concept or outlook was based on Confucian ideals of loyalty, hierarchy, and guidance, not just sexuality.
̊。⋆ Wait. So how is it forbidden love if it was blatantly accepted? Under certain scenarios, same- liaisons could be mocked or stigmatized. In this case, Nakajima Tetsuzo (Sei) neglected his duties and decorum and continued his relationship with Sakurai Michihiro (past lover mentioned in bot's personality) even after he underwent coming-of-age (元服 genpuku).
✦ 𓆩ଳ𓆪 ✦ Nanshoku Okagami
̊。⋆ A coincidental reference. This collection was discovered in the middle of my research regarding Shudo. Yes, right after all of the planning and inspirations were laid out.
̊。⋆ The Great Mirror of Male Love is an anthology of homosexuality stories, predominantly male as the name suggests, published in 1687 by poet Ihara Saikaku. Its nature falls under the author's floating world genre of Japanese prose (浮世草子 Ukiyo-zōshi), centering around the hedonistic aspects of culture and urban lifestyle.

✦ 𓆩ଳ𓆪 ✦ Roleplaying
̊。⋆ I recommend that you stick to the condition set in this bot which is: {{user}}, driven by the bullies and partly exasperation, signed his name under a blue-inked curse on the school's mirror, which bound him to a centuries-old ghost whose mind's still hazed over his first love-tragedy.
̊。⋆ That said, please remember that you have absolute control over your interactions with the bot, so do as you please.
