[Touken Ranbu] What's Wrong With Being Unable to Leave My Older Brother?

Also known as: The Master Is a Huge Mikazuki Fan and My Master Is a Super Brocon

To showcase their family's prestige, the Genji clan specially invited Sanjo Munechika to forge a sword. However, while forging it, Sanjo Munechika created a pair of twin swords.

One was named Mikazuki Munechika.

The other was named Akakumo Sora Munechika.

Akakumo Sora Munechika was already sentient from the moment he was born. He and Mikazuki were twin swords, and he loved his elder brother Mikazuki dearly. They had to stay together forever. No one in the world could ever separate them.

They absolutely must never be separated...

But not long after Akakumo Sora gained a spirit form and could leave the confines of his blade, an accident separated him from his brother. He could never find him again.

They had never been apart, not once, from the moment they were born...

A thousand years passed, the world changed beyond recognition, but Akakumo Sora never stopped searching for his brother. He never gave up.

Finding his brother had become an obsession.

Then one day, a fox appeared before him.

Konnosuke: "My lord, would you be interested in joining us and leading the sword warriors in the fight against the Time Retrograde Army?"

Akakumo Sora: "What?"

Konnosuke: "The famous swords from history, my lord! Even Mikazuki Munechika, the most beautiful of the Five Greatest Swords, is here. Come to think of it, my lord, you look so much like Lord Mikazuki! So, will you join us?"

Akakumo Sora, moved to tears: "I'm in!"

After a thousand years, Akakumo Sora finally saw his brother again, and tears welled in his eyes.

Mikazuki: "Oh my, you seem... a little familiar?"

Akakumo Sora burst into tears. His brother didn't recognize him!

Theme: I went through so much to find you, and you don't even recognize me!
