When Song Xiao was young, he wanted to become a Virtuous Official for a lifetime, but was forced to marry into the palace by that uncooperative Emperor; when his Virtuous Empress For A Lifetime career had just started, the Emperor died……

He was persuaded into playing the VRMMO 「Trailblazer」 or TB for short by his cheerful childhood friend Miyu.

But Wataru faced Miyu, who was full of motivation and said this.

「Then, I’ll be the rearguard. Shinto priest? I’ll take this one」

「What!? You are not going to fight next to me!? And you call yourself a man!?」

For some time she would become one of the top players and start getting called Hero.

So Wataru had to deal with being an extra.

But, during a certain PvP event, a strange nickname was attached to Wataru.

That, he was actually the 「Hero’s true self」.

The world is terrorized by the powerful Black Witch who has been sealed in the moon. Every ten years, the night of Hexennacht arrives and a chosen witch must battle the Black Witch in hopes of finally defeating her.

As the current decade’s Hexennacht approaches, a mysterious girl named Kagami Kagami arrives and meets Horinouchi Mitsuru, the daughter of the previous Hexennacht representative.

It takes place between Kyoukai Senjou no Horizon and the City Series, two other series by the author.
