Omniverse Chronicles: Dual Worlds of Demon Slaying
_theon
Minamiya Chiya awakens in an island nation where demons and spirits lurk in every shadow.
Fortunately, he possesses a cultivation game system.
At first, it does not seem all that impressive. He can barely deal with weak ghosts and low-level apparitions. As for the truly dangerous monsters, he has no intention of provoking them. Training quietly, staying alive, and living out an ordinary life seems like the smartest path.
That is, until one year later.
“What did you say? Your name is Hoshizuki Kaede?”
“And you have a younger sister named Hoshizuki Rin...?”
In that very instant, the dormant system finally reacts.
[Ding! The host has received an exorcism request from Hoshizuki Kaede. Complete the mission to earn generous rewards!]
Only then does Chiya realize the truth.
This shameless system was never truly asleep. It was simply waiting for the right girl to show up and issue a demon-slaying request before fully activating.
Staring at the system with utter contempt, Minamiya Chiya raises his hand in protest.
“I seriously look down on you.”
And yet, after completing the mission and tasting the rewards, he can only admit one thing.
It really is worth it.
Before long, Chiya finds himself surrounded by extraordinary girls from different worlds.
Hoshizuki Kaede and Hoshizuki Rin draw him into dangerous supernatural training.
Megumi Kato quietly steps into his life, asking whether she has finally become the heroine of his imagination.
Inori Yuzuriha offers him her song with gentle sincerity.
Moka Akashiya leans close, her crimson eyes shining as she asks to place a kiss on his neck.
Rias Gremory invites him over with a smile that is far too knowing, her every word filled with temptation.
Faced with one enchanting girl after another, all of them clearly interested in more than just his strength, Minamiya Chiya can only meet their gaze with a helpless smile.
After all, in both battle and life, these girls are destined to become the companions who walk his path with him.
In a hidden world where demons roam, urban legends breathe, and the boundary between the ordinary and the supernatural grows thinner by the day, Minamiya Chiya begins his journey of cultivation, exorcism, and fate-entwined romance.
