I, the Star Plasma Vessel, Am Here to Rob You!

Sawara Mari, a girl who had been given the title of Star Plasma Vessel since birth.

Hearing this, she smiled and admitted who she was. "I am a Star Plasma Vessel, yes. But I'm the Star Plasma Vessel from the previous generation."

The questioner exclaimed in surprise, "The previous generation? Doesn't that mean five hundred years ago..."

"Shh..." Sawara Mari made a shushing gesture. "So please don't tell anyone, because I am what people call..."

A man-eating demon.

If you tell anyone, the demons will gobble you up. (They won't, really. I'm just trying to scare you.)

To Geto Suguru, Sawara Mari was a girl with little cursed energy who could see curses. She was weak and needed his protection.

Sawara Mari turned to look at the black-haired boy's long, foxlike eyes.

"Geto, are humans and curses the only two categories you use to distinguish everything around you? Hmph. Your world must be terribly small, then. So small it's pitiable."

Geto Suguru said nothing and turned away, no longer meeting her gaze.

At the time, the boy had no idea just how "inhuman" the girl standing before him was.

That was until the Star Plasma Vessel incident. Geto Suguru saw Sawara Mari trading blows evenly with that Heavenly Restriction tyrant. The boy frowned, realizing something was wrong.

Later...

A blood-red crescent moon slowly rose behind the girl, growing from a sliver to a full moon. Nonhuman, slit pupils filled those familiar deep-red eyes.

She trampled thorns and shackles beneath her feet, then bent down and cupped Geto Suguru's cheeks. "Suguru, you have to understand that my love isn't salvation. It's a pair of shackles."

A rope can keep someone from falling into the abyss. So can a chain covered in spikes.

"So, are you willing to let me keep you prisoner?" As sorcerers say, love is the most twisted curse.

Geto Suguru gazed into Mari's eyes. Her dazzling red irises rivaled the blood-moon-lit sky, brilliant and alluring, yet radiating a dangerous menace.

After a long pause, the boy smiled faintly, took her hand, and kissed the back of it.

"I am."

Bonus scene:

During the Star Plasma Vessel incident, Geto Suguru and his friend spotted a familiar figure on their way to the building. The boy went up and grabbed her. "It's dangerous here."

Sawara Mari tilted her head as she looked at him. "By the way, Geto, is your mission to guard the Star Plasma Vessel?"

Geto Suguru nodded, unsure what she meant.

The girl smiled slightly at his answer. "What a coincidence. So is mine. Then..." She blinked. "Let's go together~"

Geto Suguru: ...?

Mari was turned by Tamayo. She's Yushiro's older sister and can see sunlight. At heart, she's a laid-back girl.

Chuunibyou stories are the best, haha. This is a record of the original blurb and the idea that came to me. I'll make some adjustments later.
