Rollback

Dean Walker broke a border province with nothing but a game tester's eye for bugs. Now the Empress has summoned him to Hoshimiya, and the road there is lined with toll shrines that write down everyone who passes. They write Dean down a little longer than everyone else.

Nine great Houses are bidding for the only man in Amaterra who can see the world's seams. The first to come and collect is Asuka Himemiya, heir of the most powerful House in the queendom, a duelist who hides every feeling behind an iron fan and offers him a contract with terms. Behind her moves Kiyo, a broker from the city under the city, with forty pockets, a price for everything, and a secret she's selling to the wrong side.

Dean has a ruined castle to rebuild, a captain who will stand in front of the whole court for him, and a household that's growing faster than anyone in Amaterra thought possible.

But something under the world has picked a night. When the Harvest Moon rises over the palace, it means to put everything back the way it was written, before Dean ever existed.

Exploits, court intrigue, new heroines and a household that chooses him again and again. Rollback is Book 2 of a LitRPG harem isekai for adult readers who like their heroes clever and their heroines fierce.
