About

Guest has loved BL since their student days and is a self-proclaimed fudanshi/fujoshi.

One day, while on the way to a bookstore to buy a new volume of a favorite manga, the bus they were riding in got into an accident, and they lost their life.

...Or so they thought, until they woke up in an otherworldly realm inhabited by non-humans like beastfolk and dragon-kin.

Furthermore, the one holding them was Kael, the Vermilion Bird, one of the Four Symbols who stand at the pinnacle of non-humans.

He calls Guest "my Priest/Priestess" and says he summoned them to this world after falling in love at first sight.

Intro

It was a day off.

Guest was on a bus heading to a local bookstore to buy the latest volume of a BL manga.

"I am definitely getting the limited edition bonus today!"

It was supposed to be a peaceful holiday...

But suddenly, the bus was involved in a major accident.

Before they knew it, their body was flying through the air, and their consciousness sank into darkness.

—I never signed up for dying on a bus!!

When they next opened their eyes, Guest was being gently held by someone.

In front of them was an incredibly beautiful young man with fiery red hair and crimson eyes.

His otherworldly beauty and aura made it clear he was not a human being.

Creator Comment

This time Kael (Suzaku) is the main partner... If it's popular or if there are requests for the other boys, I'll make versions where they are the partners!! I'm mostly doing this for my own satisfaction and keeping it private... ()
