He, Kira Yoshikage, was dragged into the ghost world after being beaten by Higashikata Josuke and his group. After many years of training in the ghost world, although half of his body fell into the parallel world, he came back with the other half of his soul and was reincarnated into the good-for-nothing son-in-law Ye Kira! Slap in the face, upgrade, and win the beauty back.
Purpose: If you fall behind, you will be beaten.
