The heroine's words are original, and her identity is Tsuna's cousin. She is eight years older than Tsuna, and one year older than Rambo Ippei. The CP's words are 18, because Orange is not good at writing romance, so...
The heroine's abilities will be revealed later, but everyone should be familiar with her.
PS: The heroine is not a Mary Sue or a Virgin. She is a bit violent. She has been instilled in her childhood that she must win every fight.
The cover, the collapse, etc. Are all just clouds.
Thank you Mengmeng for making the cover~
