This is a heartwarming (dark) story about a stunningly beautiful but ill-tempered heroine who, under the System's training, helps others day after day and treats people kindly year after year, becoming more and more sunny (twisted).
System: A new mission has been posted. Host, earn 50 vitality points within the time limit. Keep it up, girl! Work hard and become sunnier and sunnier! (^O^)
Heroine: ...Oh, really? Why should I go through all this trouble? You little (bleep...) (♯`∧′)
System: Oh, don't you want to live anymore?!
Heroine: ...Fine, I'm going right now... (╥﹏╥)
Reader's guide: 1. This story features the worlds of Inuyasha, Prince of Tennis, One Piece, Bleach, Vampire Knight, Naruto, Katekyo Hitman Reborn, Death Note, and Harry Potter.
2. The heroine is gorgeous, lazy, completely unmotivated, and a total clown. With the System's help (training), she'll become full of energy (not really).
3. About the hero: What's a hero? Can you eat one? What? You say he's important? Fine, then... I'll pick whoever I happen to land on!
Come on, I'm waiting for your growth.
