Quick Wear: The Female Supporting Character Awakens and Doesn't Leave

The heroine is a wood + space mutant in the wasteland world. She is determined to save her own world. She is chosen by the system and goes to the small world to complete tasks and earn points and merits.

The heroine is not a selfless deity, she has normal emotions, so if she's attracted to someone, she'll fall in love. If they're not, she'll stay single. It's completely up to her, so some small worlds have couples and some don't.
