Being a Guardian Is So Stressful [Katekyo Hitman Reborn]

It's not fair! Why should this happen? That guy Bai Lan destroyed countless parallel worlds, yet somehow his world is still part of the proper timeline! But my world has become a Lostbelt. All because Sawada Ieyasu never became the first boss of the Vongola Family? Wasn't he perfectly happy being the Vongola's top enforcer? The Second inherited the position just fine after the First stepped down, the Ninth is still the Ninth, and Reborn, the world's greatest hitman, even came to Namimori to train Sawada Tsunayoshi! So why did our world become a Lostbelt? Why is it being destroyed? Why can't the timeline continue just because someone else became the Vongola Primo? Huh? You want to know who I am? I'm Rokudo Mukuro. More precisely, I'm Rokudo Mukuro, a sixteen-year-old girl and a Guardian. Don't get the wrong idea! I'm not a Guardian of the Mafia. I'm the real deal: a Guardian of the Counter Force, under contract with Alaya! So what if this is a Lostbelt? Sure, I haven't had a very happy life. I was locked up and experimented on, hunted, betrayed, and hurt by people I trusted. But even in a world that cold and cruel, there are things that matter to me. Why should my world be destroyed? You've got to be kidding me! Hey, you stupid laws and rules, look up! You're flying in the sky!! [PS:] [This blurb is for reference only.
