STORY

After all the large kingdoms joined together, war disappeared from the world.

However, for the persecuted small countries, little changed.

Among those persecuted countries was the Succubus Kingdom.

And so their lord forfeited a large amount of tribute to the humans

in exchange for an alliance that would help them.

The night the alliance was forged, the lord held a large celebration,

and invited many humans to the caste. Finally, the succubi would be free of oppression.

However...

「Human soldiers are suddenly assaulting us! There's a huge commotion downstairs!!」

It was all a trap.

For the succubi, there was little they could do about it.

However, the lord's quick wits allowed them to help their daughter and heir Reina escape.

However, Reina, wanting to solve the mystery of what happened, and who the culprit is,

returned once more to the castle...

The three things she would need to find out:

『Whodunit - Who is the culprit?』

『Howdunit - How did they commit the crime?』

『Whydunit - Why did they do this?』

Powerless Reina's battle began...
