Has Dazai Maxed Out His Affection Today?

[The story gets extremely messy in the later stages, starting around worlds five or six. Proceed with caution, and ideally don't read it.]

[Worlds seven and eight are in the bonus chapters.]

After Dazai's suicide, he was trapped in a chaotic void, drifting for an unknown length of time until an unknown System came to him.

A pact to travel through nine worlds in exchange for one true death.

Dazai gladly accepted.

But what Dazai never expected was this:

His nemesis Chuuya would be in every world.

In every world, he would have to roleplay with his nemesis without breaking character (in public).

And in every world, he would have to max out his nemesis's affection!

Dazai: I'm so tired. I don't want to die anymore.

"An endless darkness and emptiness, even after death."

"In a world where nothing exists, you alone are my salvation."

The nine worlds:

(1) The Personal Attendant of Young Master Muzan [Complete]

(2) I Am Dazai. What Do You Want? If It's Nothing, Leave Me Alone While I Read Fanfiction [Complete]

*(3) What Should I Do After Falling Into a Harem Fantasy World With Cultivation and Weird Fetishes That Has Nothing to Do With the Plot? [Complete]

(4) The Bizarre Case-Solving Adventures of Phantom Thief Dazai and Famous Detective Chuuya [Complete]

(5) Sexy Chuunibyou, Dazai Live! [Complete]

*(6) Interstellar Magic University (Not Normal Magic, Not Normal Space) [Complete]

(I really don't want to write a tenth world, sob. Wouldn't it be better to have them get engaged in the ninth world and then return to reality to get married?)

Premise: Living for you.
