Description

Supplied by the Steam store

The Scarlet sisters accidently annoyed—Reimu Hakurei—resulting in the Scarlet Devil Mansion meeting a tragic end and being ruined overnight.

Flan could only watch her former home in despair, standing helpless among the ruins...

Left with no choice, Remi and Flan had to bite the bullet and build everything back from scratch. Just then, Remi remembered an abandoned Scarlet Mine located to the east of the old mansion...

=========================================================

Featuring

Seeing cute Flan who is mining strugglingly

Improving the attribute by using EXP to level up

Purchasing the item from the shop

Recruiting the companions by using Gems

Finishing the diverse Achievement

And rebuilding the Scarlet Devil Masion eventually...
