Today's Sun Pillar Is Still Being Confessed to by His Disciple

After the battle in the Infinity Castle, Tanjiro finally killed Muzan with everyone's help, though they had paid a terrible price.

"Don't leave me behind... Tanjiro!"

Tanjiro: I won't even give you the time of day.jpg

When he opened his eyes again, he was in another world, where he had become the Sun Hashira of the Demon Slayer Corps.

But where were the other Hashira?

Tanjiro stammered, "Mr. Giyu, where are Muichiro and Miss Shinobu?"

Zenitsu looked confused. "Who are they?"

Not only Zenitsu, but even the Master had no idea who the people Tanjiro mentioned were.

There was nothing he could do about it, so Tanjiro decided to focus on his work as the Sun Hashira.

A week later, he rescued a brother and sister from a demon during a mission

"...Mr. Giyu?!"

This was only the beginning.

The Butterfly sisters, the Tokito brothers, Mr. Himejima... One by one, the friends who had fought alongside him appeared as children, and Tanjiro rescued them from demons.

Tanjiro was satisfied, until one day he found the words Alpha and Omega in a strange foreign text, terms Zenitsu and the others often used.

Tanjiro: "?????"

There are six genders in this world!!!

What exactly is an Omega? He seemed to have had a strangely mistaken idea about this gender before!

Before Tanjiro could figure it out, several Alphas surrounded him.

Kyojuro: "Tanjiro! When I become the strongest Alpha, please make a vow with me!"

Giyu: "I was my teacher's first."

Zenitsu: "Tanjiro, if you choose someone else, I'll jump from here, Waaah!"

...And there were plenty of others.

Tanjiro crouched with his head in his hands. Deep in his consciousness, he seemed to hear Muzan's mocking laugh again:

Hah, you won't even give me the time of day?

Giyu had never understood why his master chose an ordinary person like him as his successor.

Kyojuro had also never understood why the Sun Hashira always looked at him with a sad, nostalgic expression, as if he were seeing someone else through him.

Until one day, they gained another set of memories.

[Note]

A happy ending with everyone together. How many people end up together depends on how the story develops later.

All Tanjiro, primarily Tanjiro/Giyu and Tanjiro/Kyojuro, with lots of Alphas competing and fighting over him. The main story has separate endings: Giyu and Kyojuro each get an ending with him, both are 1v1 endings, and the others get their turn in the extras.

Age manipulation inevitably leads to some OOC.

UzuTanjro, since Tengen and his wives are split up.

ObaMitsu, KokuShino, and Yushino stay together, though their top and bottom roles will switch.

The fights serve the plot, so the power scaling may fall apart.

Contains a little Mitsuri as an Alpha and Obanai as an Omega, a little Mitsuri as an Alpha and Koku as an Omega, a little Yushiro as an Alpha and Tamayo as a Beta, a little Kaoru -> Shinobu <- Megumi, and three Alphas.

There will be original demons who aren't important to the story.

There are no pairings other than the ones mentioned above.
