I Made a Contract with Otsutsuki Toneri, and Got the Tenseigan from the Start!

This is a world where everyone practices ninjutsu! At eighteen, anyone can awaken a talent for ninjutsu. Chu Mo awakened three talents: S-rank Mangekyo Sharingan, S-rank Dust Release, and B-rank Byakugan. Everyone thought Chu Mo would choose either the Mangekyo or Dust Release, but he chose the Byakugan instead. “Is Chu Mo crazy? He had the Mangekyo to choose from, and he picked the Byakugan?” “The Byakugan has some unique uses for scouting and taijutsu, but its potential is too limited. It can barely compare to the three-tomoe Sharingan. How could it possibly measure up to the Mangekyo Sharingan?” But they didn’t know... Chu Mo’s Byakugan wasn’t an ordinary Byakugan. 【Form a contract with Otsutsuki Toneri to obtain the Otsutsuki bloodline!】 【Convert the Byakugan into the Tenseigan?】 “We’re breaking up. I was completely wrong about you!” The campus belle, Jiang Shanshan, was furious. “You could have chosen an S-rank talent and helped me restore my family, but you chose a mere Byakugan! You did it on purpose. How can you be so selfish?!” But before long, everyone noticed that something about Chu Mo’s Byakugan... seemed a little strange. “Why can he absorb my ninjutsu?” “How can he use chakra mode? Does he have a tailed beast inside him too?” “What are those black orbs around him? Why don’t my ninjutsu work on him?” “Strange, why did the sky suddenly go dark?” “It looks like Chu Mo... pulled the moon over here...”
