You Waited Until After I Won Over the Moon Pillar to Tell Me You'd Picked the Wrong Person to Save

Tsukichi Genkai was an ordinary high school senior when one day he got saddled with some strange thing calling itself a salvation System.

It rubbed its cybernetic hands together and asked for his help, but the moment it mentioned going to a dangerous Warring States era full of fighting, Tsukichi Genkai flatly refused.

"Thanks, but no thanks."

[The reward is an acceptance letter from the University of Tokyo.]

"Well, now that you mention it..."

For the sake of that University of Tokyo acceptance letter, not that he was a kind person or anything, Tsukichi Genkai decided he might as well run an errand for the System.

He had barely arrived in the Warring States era when the System started babbling in his head.

[Don't worry about the danger. I've spent a fortune loading you up with the world's strongest cheat! Now, the person you need to save has a truly tragic fate. His abusive father doesn't love him, his poor mother died young, and he has to support the family all on his own. Then disaster strikes, and he spends his whole life wandering from place to place. In the end, even his death is so lonely and miserable... Sob, listen, his name is Koku]

With a snap, the System went offline and didn't make another sound.

Tsukichi Genkai: ...

Tsukichi Genkai: Koku what? Hey, hey, don't stop halfway through the most important part.

Oh well. At least he knew the person was from the Koku family, and the System had described his past in detail. If he went to take a look, he should be able to figure out who it was...

Right...?

Tsukichi Genkai stared speechlessly into the wide eyes of the Koku twins.

...Which one was it?

Much later.

The System finally came back online, very late indeed: [I'm finally back, Host! I didn't realize that cheat I got for you was so expensive. It took me forever to reconnect! But you're such a great Host, so you've surely already finished...]

Seeing the modern electric lights, it let out a shriek: [How are you still alive in the Taisho era?! You've become a demon!]

Seeing the former Moon Hashira lying beside Tsukichi Genkai with his eyes closed, the System shrieked again: [How did you end up with Kokushibo?! What about my poor, lonely, helpless Child of God?!]

Tsukichi Genkai, who had become the ruler of the world: ?

The Hashira, whom it had called Kokushibo: ?

The Demon King Yoriichi, happily planting flowers in the backyard sunshine: ?

#Save the one you were sent to save, then save the one you were sent to save#

#I finished winning everyone's hearts, and only then you tell me I got the wrong person to save??#

* The pairing is Genya. The male lead is the seme.

* Important warning: The male lead's cheat is Sun Breathing. Early on, he'll use the secret identity of a Sun Breathing reincarnation to carry out his mission, and Genya will feel a little forbidden, bittersweet tension as they get to know each other because of the male lead's secret identity. (But it's honestly so delicious, please forgive me, I'm very sorry, kowtowing in apology...) Overall, it's very sweet, no angst.

* People keep asking where the despicable boss went. Haha, after overcoming the sunlight, the boss is settling down obediently as the second in command (

* I'll do my best to serve up a delicious Genya feast. A happy ending for everyone. It should be a short story, not too long.
