Resist Extra Dimensional

Gates between worlds have torn open, and Agent No. 01 of R.E.D is the one sent through them to clean up the mess. Modern soldiers, fantasy monsters, and a very thin line between rescue mission and undercover assignment.

The job splits in two: fight off otherworldly threats leaking into the real world, and pose as an ordinary student at R.E.D's academy while the actual work happens off the books. Both halves put you in constant contact with the same group of women, and the story treats that contact as the real objective.

You play through missions and academy life while managing relationships with the heroines around you, and your choices decide who sticks around by the end. The harem outcome is on the table, but it's not handed to you.
