Even a Desktop Pet Has to Save the World

[Main story complete. Extra chapters will be posted occasionally.]

Tsuna Sawada, who faked his death, is accidentally intercepted by a System while switching places with his ten-years-younger self. He is forced to become a desktop pet in a desktop pet app.

Tsuna Sawada looks dead inside. What kind of lousy System is this? A desktop pet can save the world???

The Tenth Vongola Boss, selling cuteness online.

Eighteen-year-old Osamu Dazai sees a desktop pet app that has mysteriously appeared on his phone. After testing it several times, he finally opens it, only to be bound by an annoying System and forced to raise a brown cat named Tsuna by completing missions.

Osamu Dazai gets it. The lousy System is tricking him into wasting time and spending money.

Then he gets hooked. Pet a cat for a moment, feel happy for a moment. Pet cats forever, feel happy forever.

Note:

1. This blurb is provisional and may be changed later.

2. This is a self-indulgent story, and the characters may be very out of character. I'll do my best to keep them in character.

3. The side-story worlds are all provisional. If there's something you'd like to see, feel free to suggest it. I'll consider adding it, hehe~

4. I have a day job, so updates will be whenever I can manage them. I'll try to update weekly, though I may post two or three times a week.
