Hyuga Tenkyō is a recognized genius of the Hyuga clan. He could recognize a thousand words at the age of three, recite ancient poems at the age of five, was familiar with the theory of ninjutsu at the age of seven, and created his own soft fist and Tai Chi at the age of nine!

However, when he was twelve years old, Hyuga Tenkyō was unable to even refine chakra. Every time chakra was refined, it disappeared into thin air. Not to mention ninjutsu, he couldn't even use physical techniques.

Oggs transmigrates to the Dragon Ball world and obtains the Multiverse Shock System. By simply acquiring a certain amount of Shock Points in other worlds and completing World Shock Missions, he can obtain generous rewards such as increased combat power, Super Saiyan 1, Super Saiyan 2, and even subsequent realms.

Thus, the following series of events unfolded.

——————

Jujutsu Kaisen World:

Under Su Nuo's utterly shocked gaze, Oggs withstood countless slashes without moving an inch:

"You are the challenger."

——————

Demon Slayer World:

Muzan's face was filled with resentment as he growled at Oggs, "Damn it... if there were no sun..."

"Oh?" Oggs smiled knowingly. "You mean... the sun is your weakness?"

After speaking, before anyone could react, he slowly raised his right arm, energy gathering in his palm, and pointed it towards the sun:

"Okay then."

"If I blow it up, you'll be able to fight me, right?"

——————
