Alex is a dog.
The soul passes through the dog.
His master, a famous madman in the empire, is determined to train Alex into a muscular dog that can go to the battlefield and drive a mecha to destroy a warship. He calls this process nurturance, you are my son and I am your father.
After going through many hardships, Alex finally regained his human form. He went to settle accounts with his former owner despite being a tall man of 1.95 Meters, and his wrists made a clicking sound.
Then, he still couldn't beat it.
"Be good and call me daddy."
Purpose: Use adoption instead of buying. It is everyone's responsibility to love dogs.
