My job is to be the man behind the protagonist, or, in short, the protagonist's right-hand man. The protagonist's right-hand man is invincible in every story, so naturally, my power is invincibility. How lonely it is to be invincible~
At my superior's request, I was born this time in a serious comic. The protagonist, who is also my new boss, is a gloomy, pitch-black man, even darker than me: Mr. Wayne, the dark and brooding one!
Seeing as he's rich, well-endowed, has a great ass, and a pair of blue eyes you could drown in, I'm willing to work for him for free.
Bathing him, dressing him, feeding him, keeping him warm, putting him to sleep, acting as his ride, beating up bad guys, filling in for him at work, repairing his gear...
I can even manage his mobile games!
Where else could you find such an excellent workhorse? (Proudly strikes a hands-on-hips pose.jpg)
But one day, Mr. Wayne suddenly made a request I'd never heard before: he wanted to kiss me on the mouth.
Th-th-th-this...
I can't do that! I don't have the necessary equipment! It's impossible!
Mr. Wayne, please stop coming closer!
One smoke-black figure vanishes at lightning speed, while another black figure with cat ears stays put, rubbing his chin as he ponders the suddenly pink title above the other's head, which stretches off into the distance:
(Pink) [Yes yes yes yes yes kiss me already yes yes yes yes yes...].
Hm? So he's not asexual after all.
Bruce's guardian spirit is a black ghost wrapped from head to toe in bandages. It's even more capable than Alfred, but hardly ever speaks.
Strange words occasionally appear above its head. At first, they are a string of gibberish no one can read. Later, black words or phrases appear from time to time.
Things like [Idiot], [Annoying carbon-based life-form], and [Hopeless obsessive], as if they were titles.
After a while, the titles above the guardian spirit's head change to [The Best Dark Knight in the World], [I Want to Hug You So Much], and [Look at Me Already], and their colors become more varied, too.
Maybe the guardian spirit's titles are evolving?
When Bruce tries to touch its head, it obediently bends down. Its shoulders twitch gently in time with his strokes, and the title above its head turns bright pink.
(Bright pink) [Don't stop].
Oh... Bruce gradually understands everything.

1. There probably won't be any Batfamily. I can't write ensemble casts, and I'm afraid I'll mess it up.
2. The protagonist isn't human. You can think of it as a stand-in made of black particles. This isn't an Ajin fanfic, though I did borrow the IBM concept. I didn't tag it as Ajin because that would put the story under anime and manga.
3. No fixed pairing roles. The headcanon is extensive, so blame me if anyone is out of character. Given the IBM concept, the pairing could be considered a form of selfcest. The blurb's tone differs somewhat from the main story, so please keep that in mind.
4. It should be a lighthearted story with a serious plot, I think. I want to write a silly story where, through a series of misunderstandings, they end up winning each other over.
5. I'll add anything else that comes to mind.
The first version of this blurb was posted on October 17, 2025, and has been screenshotted and archived. I'll revise it whenever I like before the story begins, but the core idea won't change.
