One Piece: I am Imu

It hadn't been long since he had consumed the Devil Fruit, and Longinus could already feel his body rapidly heating up. As the temperature rose, his skin began to emit a faint reddish glow.

Soon, dense, shiny reddish scales began to form, reflecting a faint orange glow.

It wasn't long before golden, slightly curved horns sprouted from his forehead. His fingers lengthened and ended in sharp claws. A scarlet tail emerged from his lower back, and dark, spiny wings momentarily unfurled from his back before contracting.

"This power..."

With a body that had grown to over three meters tall, Longinus could clearly feel the overwhelming strength flowing throughout his being.

"Enough! If you keep this up, you will destroy my office. Later you can test your powers in the open air." The director said, looking disapprovingly at the white carpet, now destroyed and covered in black marks.

"Yes."

Longinus immediately withdrew the power of the fruit. His body began to rapidly shrink back to its normal size in a matter of seconds.

"Your second graduation reward is this."

The director walked to the wall, where he took down a long sword in a red scabbard and handed it to Longinus.

"It is a weapon that the Cipher Pol found in the ruins of an ancient sarcophagus on Asuka Island, in the first section of the Grand Line. This cursed sword has been sealed for over a thousand years."
