The 5 Cm Tenth Generation

The Tenth Vongola boss discovers that even when he's shrunk to a mere five centimeters tall, he still can't escape his tragic life, as the wheel of fate runs him mercilessly over. Somehow, he ends up back ten years in the past and gets kept in a teacup by his own Storm Guardian. And then one troublesome thing after another comes along... If you could meet your past self one day, would that mean the future had already slipped away? Drawn by my friend Shasha~ Apparently, this story's joke titles include The Tenth Boss in a Teacup, Little Tsuna's Big Adventure, and The Pea Princess 270. The author says the above titles without book-title marks are all just nonsense. Thank you all for your love. I'll do my best to repay it >< Especially my dear sister Tumi, who helped tease the inspiration out of our chat.
