Living in Fengdu, starting from being adopted

After traveling back in time as the nine-year-old Tokiwa Sougo, on April 2009, 4, he finally remembered his past life's memories, but at this moment...
Sitting on the bus for the spring outing, the driver is Wang Xiaoming, Tsukuyomi is standing next to him with a gun, and Swartz is standing in front of the bus
"Maru spicy!"
After a near-death experience, he was sent to an orphanage. He thought he would be adopted by his uncle according to the original plot, but he didn't expect that the person who came to adopt him was a black-hearted doctor with bad intentions, the weather-mixed body transformer Isaka Shinkuro. Then, he was sent to the black-hearted hospital in Fuuto.
Just out of the tiger's den, into the wolf's den
"Maru spicy!"
