A male or female protagonist (teacher, delivery person, childhood friend, online gamer) becomes aware of the hikikomori sister. Initially, they connect with the caregiver sister —but slowly, they are drawn to the withdrawn sister's hidden depth, intelligence, or artistic talent.

The game uses point-and-click mechanics to simulate daily interactions within a confined environment. Point System:

Predators specifically target hikikomori individuals online, knowing they are lonely, financially dependent on family, and unlikely to report abuse. The sister often discovers this too late—or becomes complicit by not wanting to "control" her sister's only emotional outlet.

These points are used as currency to unlock new sexual positions and situational scenarios. Unlocked Actions:

PicBackMan does exactly what it's supposed to. It's quick and efficient. It runs unobtrusively in the background and has done an excellent job of uploading more than 300GB of photos to 2 different services. After having lost a lot of personal memories to a hard drive crash, it's nice to know that my photos are safe in 2 different places.

LOVE this program! Works better than ANY other program out there that I have found to upload thousands of pictures WITH SUB-FOLDERS to SmugMug! Thank you so much for what you do! :) #happycustomer

I pointed PicBackMan at a directory structure, and next time I looked - all the photos had uploaded! Pretty cool. I use SmugMug and while I really like it, the process of creating directories in is pretty laborious when you need to make 80+ at a time. This was a breeze. Thank you!
