[No system + Gardevoir heroine + deserted island start + parallel world + city + daily warmth + non-invincible text]

You start out as a stunted unicorn beetle wandering on a deserted island. Do you want to go?

Whoever wants to go can go!

Send the power of bond and understand the language of elves.

Think about it.

You may encounter a shiny Lalulas occasionally and capture it.

Quite interesting.

Evolved Gardevoir, devoted, only loves you, wants to climb into your bed every day.

Stop talking, who else but me!
