"Because adults know their ceiling."
"When people grow up... They discover their ceiling, the limit of their potential. It gets ever closer as we age...so close we can see the stains on it. But you can't see your ceilings yet, and it's better that way. The only thing hanging over you is [the] infinite sky, you can grow as strong as you need to be!!"

Mikihisa Asakura makes his first appearance when he spies on Yoh Asakura who is relaxing after encountering Lyserg. He reports to Yohmei about the appearance of Hao Asakura. Next scene, he helps Anna, Manta, and Tamao find the way to the Patch Village. In a strange scene, Mikihisa is seen looking at the Great Spirit with a sad face.
Mikihisa first appears in the stands during the massacre of team X-III by the hands of Hao Asakura. He explains to the spectators about Hao and meaning of the pentagram. The pentagram symbolizes the five elements: water, fire, metal, earth, and thunder. Since Hao masters the pentagram, he can change his spirit of fire into water at will.
While Yoh has finished explaining to his friends that he is Hao's twin brother, Hao has over a million mana, and Hao is going to win regardless of what they do, Mikihisa and his wife finds Tao Ching and his family in the visitors' area. After Keiko convince Tao Ching that the Ultra Senji Ryakketsu is powerful and Mikihisa tells him that he can make Ren strong, Tao Yuan steps in and wants to test it. Mikihisa gladly accepts his challenge since he is a father like him. He finds Ren and his team on the bridge. Mikihisa answers Chocolove's question about destiny when he says that power is necessary to create one's destiny. He says that Hao has the greatest power than all of us. Mikihisa explains that he will teach Ren and his team the Ultra Senji Ryakketsu. When Ren tells Mikihisa that he gets strong his way, Mikihisa provokes with his attacks to get Ren to fight him. After Ren mocks him that he cannot prevent a newborn from escaping, Ren attacks Mikihisa. He notes that Ren has done well to figure out his illusions are his oversoul. When Ren uses his new oversoul, God of War, on his mountain spirits, Mikihisa still has his oversoul intact. He tell Ren not to jump to conclusions. Mikihisa congratulates on Ren’s change when he learns that ghosts have feelings, defy his family, and swore to never waver again. However, Mikihisa states that Ren’s oath is a weakness to control his wavering heart. His statements enrages Ren to charge at him. Mikihisa easily grabs Ren's head and slams it into the ground. Then Ren gets up and attacks Mikihisa, but Mikihisa easily dodges his attacks. He lectures Ren about how oversouls do not cast shadows. As Mikihisa grabs Ren and slams him into the wall, Ren mumbles to Mikihisa that he will not waver, Mikihisa gets a kick the face. Although Ren has finally landed a hit, Mikihisa denies it. The battle ends with Mikihisa knocking out Ren.
As soon as Ren wakes up, Mikihisa has already provided barbecue to his teammates. He offers Ren some special mountain barbecue. When Ren rejects it and asks him why such strong adults let their children fight, Mikihisa says that adults have already reach their limit whereas children, who are still young, have plenty of time to get strong. Suddenly, Nichrom and Magna appears. Mikihisa finds out that Magna is hunting his teammates, Redseb and Salerm, and the next match is starting. Mikihisa is a contender in the shaman king fights with his team Kallabahers because Mikihisa is on a quest to stop Hao no matter what. When Magna tells Mickey that the age of his kids does not matter to the Spirit of Fire, Mickey gets mad. After Ren tells Mickey to go and help his teammates, Mickey tells Ren not to jump to conclusions and to underestimate them. Mikihisa rides his mountain spirits and goes off.
