Hi~ Hello everyone, my name is Xingyue Chengkong, I am 10 years old this year
My profession is a killer, and my hobby is to play with the ten generations of the Vongola family by reborn my master (ahem, of course, training -).
Recently, I have been busy helping a loser review his homework. Alas, he became a teacher earlier than me (did he become a teacher? When~) and he is 10 years older than me. I am depressed.
