The doctor said that he wouldn't live past a year, on the night he was born the 2 tails lightning wolf's Jinchuriki Died of old age, before it got released from the seal it was in, the Father quickly sealed it in Markus, if a Beast the strong in Markus, he was saved from death and when he turned 5 his Brother and an unknown man killed the Herada Clan, when markus walked out of his room he was greeted with a hallway full of blood, the masked man fled the scene leaving only Markus' brother Tsume, Markus: "why did you do this?" Tsume: "because i wanted to test my power and so then i could become more powerful." Tsume starts Laughing uncontrollably, Markus' heard a voice in him: "if you want power just trust me and you can do whatever you want to him" Markus didn't know what to do and just ran at his brother with killing intent, his brother was more skilled than him in the art of fighting and Markus was useless in that fight, his brother disappeared and Markus got back up and in a fit of rage his Chakra skyrocketed to tailed beast level as he went on a rampage in the hidden cloud, he was up against the strongest Jonin of the Shi Clan, Ōkami was no Match for the Rampaging Jinchuriki, with a barrage of attacks with a blade made out of pure chakra, Ōkami was almost out of Chakra and when he blinked his body was cut in two from one swift attack from Markus' blade, Ōkami the Demon eyed was no more, and when that happened the leader of the Shi clan showed his face, Markus went to attack him but was restrained and had his Chakra drained by three members of the Shi Clan, one little girl went up to markus and hugged him, her name was Ai, Ai calmly said: "its ok, there nothing to worry about you're safe" with those words markus' chakra went down from tailed beast level back to normal level of chakra, Mokushiroku took the eyes out of Okami and infused it into Markus' eyes, Markus' eyes stayed the dark blue color they were before, when he woke up the next morning, he was being watched by the girl, Markus: "where am i and who are you?" Ai: "i am Shi Ai but i get called Ai-Chan and you're in the Shi Clans main house" Markus not remembering what happened yesterday because he rejected the memories, when Mokushiroku and Shurui walked into the room Markus sat there with a frown on his face, Shurui: "Ai-Sama can you please leave this room for a minute" Ai left the room, Mokushiroku: "Markus we are Adopting you into our Clan, you're now Markus Shi" Shurui: "nii-san dont say that, he can keep his last name Herada" Markus sat there then got up walked up to Mokushiroku and punched him, Markus: "do you think i will accept that? i'm not a Shi and i will never become one" Shurui: "Markus how about i adopt you into my side of the clan," Shurui smiled, Markus: "i will be ok with that" he blushed.
