The real world depicts the daily life of living, and the spirit world depicts an unearthly world filled with spirits. Two separate worlds intertwines at times, and the unresting dead spread terror in the real world. A girl seeks to vanquish the terror that took away her mother, so she took their power to enslave them, by overwriting the grudge of dead by another.

Yayoi Houdzuki, a girl with spiritual awareness, captures ghosts to create an army to beat a ghost that took her mother away. Along with her cousin, Eiko Houdzuki and her tutor-turned-bait, Keitaro Gentouga, Yayoi has captured multiple super strong ghosts she named 'Graduates' to fight a evil malevolent deity, Taisui Seikun, who intends to take their new friend, Ai Kamyo as his bride, resulting in her death when she turns 20. After covering the entirety of Kyoto with a massive curse, unexpected help from new allies, a very deadly battle and the revival of a great spirit has finally put an end to the god. The god has finally been captured by the trio, however, they have been injured badly. After some rest at the hospital, Keitaro and Yayoi went to take a walk outside while Eiko still recovering.

S-So, we have finally defeated the god, right? Keitaro asked with a hesitating voice as he still couldn't believe it.

Yayoi glanced towards him and then looked towards the alien doll.

Yeah, we have finally put an end to this but it's been 3 days already, Ai's family haven't made a move yet... i dont know what they will do.

Keitaro thought about it and said, "Could it be that they are happy with the god being dealt with?

While it is possible, i doubt they would let go of this matter without even any interrogation and they didn't even came to check on Ai till now even when we are in Kyoto.

"Hmm....?! Yayoi-chan, what is that!?" Keitaro asked while pointing out at the mysterious white mist.

"Mist in this season and at this place? It's definitely not natural, is it a curse? Yayoi thought while grabbing Keitaro and taking him in opposite direction of fog.

Despite their efforts of dodging the fog, they were finally caught in it. After an instant, both of them were at a completely different place.

"W-What j-just happened here!? We were at the hospital right!? The mist surrounded us and.. where are we?" Keitaro spoke in a really frightened tone.

"Calm down Keitaro, we need to stop panicking and find out about our current situation". Yayoi said while looking around the place.

While they were still confused about their situation, Keitaro suddenly feels chills down his entire body. "W-What is this feeling, it's not powerful but the numbers are overwhelming"!

After listening to Keitaro, Yayoi tries to see the ghosts using her eyes and what she saw was a horde of ghosts almost everywhere, none of them were nowhere near as strong as a graduate but their sheer number could make Keitaro feel like he is in the presence of a graduate!

Appearance of a mysterious mist, arriving at a new place. Where are they? Can they survive in this unknown world? Can they go back to their friends?
