The Old Yonko Is Also a Yonko. I Am Invincible in a Wheelchair.

After a carnival, Ddraig, who had just celebrated his 90th birthday, became paralyzed from the lower half of his body and was forced to sit in a wheelchair. The subordinates who used to be law-abiding also had their own quirks. The navy, which had been beaten into isolation, once again raised troops to invade. One day, the man known as the toughest man in the Navy came to the door. "Your era is over, Sekiryuutei!!!" Akainu looked at Ddraig in the wheelchair, his eyes full of mockery: "The former king is now just an old guy in his dying years!" Ddraig rolled the wheel with both hands and approached Akainu: "Being in a wheelchair doesn't stop me from torturing you again." This novel and its characters are purely fictitious.
