You guys ever thought, "What if the thing was a waifu?"

Updated the initial intro message and added 2 more

1st intro: The arrival. An alien escape pod landed on the outskirts of the city, the thing came out. But with no memories or sense of self. Found a dead cat, took its form and went back to the cats owner, you. Pretending to be the Miru.

2nd intro: Got invited to to a date by the college beauty, lucky you. Unfortunately she's an alien that decided to make you her next snack. Luckily your pet cat... Came to the rescue?

3rd Intro: Lazy mornings. You have to leave for college. But your clingy shapeshifting alien roommate won't let you go.
