Season 1

The grave of a man named Chou Shakurin has been disturbed in the Chinese countryside. A girl named Houhou, claiming to be the granddaughter of the grave's occupant, appears there. At the same time, Chou Soran, a student at a college in the city, has returned to the countryside to visit his grandfather Shakurin's grave.

The morning after the zombie attack, Soran returns to college. Houhou tells him that she’ll be going to the same college he is, and she asks him to show her the power he used to fight the zombies. Soran jokes around, but Houhou takes out her knife and attacks him. Soran refuses to fight back, remembering his grandfather’s words. The time to use the power that his father, Yotoku, made him practice when he was young... Then, something envelopes Soran’s body. As the two of them fight, Ro Ryou, who physically looks like a young boy, and the zombie who defiled the grave are gathered in an abandoned building somewhere. At their feet is Shakurin’s body, and a beautiful woman named Natsuka appears as well. Now, Soran has no choice but to fight, and Natsuka, Ro Ryou, and the Zombie are beginning to make their move as well. What did Shakurin leave to Soran when he died? And what will Soran do now that he remembers Shakurin’s words?

Not only has he become Houhou’s servant, but now his roommate is calling him suspicious! Just as everything’s going against him, Soran gets a friend request for a social network on his phone. And it’s from a cute girl! Soran gets excited, but Houhou tells him there’s someone she wants him to meet that evening. Soran wants to go on his date, so he ignores his master’s phone call. The girl who appears at the meeting spot is Kenken, who is as cute as her picture, and very kind as well. Meanwhile, Houhou is with Jo San, who she was supposed to introduce to Soran that night. Infuriated, she uses GPS technology to track him, saying that she’ll need to give him a very harsh lesson. What will happen with Soran’s date? Will Houhou find him? What will happen next?

Excited by his first chance at a date, Soran is easily deceived by Kenken and his Kinkou is sealed away. Natsuka, Ro Ryou, and Kenken capture him. Houhou and Josan come to save him. A battle begins as the helpless Soran is left tied up in the corner. As more and more outsiders and zombies join the fight, Soran is saved by a new power user, Saru. The place becomes a war zone as all the outsiders use their powers. The capture of Soran brings the two outsider organizations into open conflict. Who will survive? And what will happen to Soran?

In the prison on the bottom floor is Kenken, who was betrayed by Zensei and captured by Express Delivery. Jo San tries to get information about Zensei from her, but she refuses to talk. Suddenly, Jo Yon, his older brother, appears, and when she won’t answer his questions he tries to use force. Soran tries to stop him, and it feels like a battle could break out in the prison at any second. Soran wants Jo San to go easy on Kenken, and Jo San is about to agree, when Jo Yon interrupts and refuses. At last, Kenken talks. Why did they steal Chou Shakurin’s body? What does Zensei want? Why did Kenken try to join Zensei? The truth is revealed.

Soran is kidnapped, and met by Chou Reigyoku. Reigyoku uses kinkou, the techniques that Soran was taught by his father when he was little. His kinkou is more powerful than Soran’s, so Soran has no way to fight back. At the same time, Houhou goes to save him, but Fuu Saen blocks her path. As the two of them fight, they can feel Reigyoku’s ki off in the distance. They agree to a temporary truce and go towards Soran and Reigyoku. Soran is about to give up in the face of Reigyoku’s overwhelming might. Houhou arrives and says, “Show him your power!” His grandfather, Shakurin, had taught him a power even stronger than kinkou. Soran’s kinkou begins to change color. What power does he have?

Soran has become a Tenshi candidate, and now he lives in a villa with Houhou. When she sees how nervous he becomes when he’s alone with a girl, Houhou decides to make a man out of Soran. Soran is angered by her selfish decision, and says he’s not going to listen to her anymore. He leaves the house, and Houhou is left standing there alone. Fuu Saen of the Tengekai is waiting for him. Soran is taken to the Tengekai, which is actually a huge corporation called the Tenge Group. He is met by Fuu Saen’s father, Fuu Chonhao, who is the leader of the Tengekai.

Houhou goes to the Tengekai to take back Soran. She defeats one outsider after another, but then she is stopped by Ja Jongu. He is on a different level than the other foes, and she can’t even touch him. Meanwhile, Soran is with Saen, who has been told by her father to date him. The seal doesn’t respond to Saen! Saen is serious about dating him so Soran runs away. Saen says if he’s serious about running, she’ll stop him with everything she has. She uses her teleportation powers to attack him and he has no way to fight back. Both he and Houhou are losing the fight. Two battle take place inside the Tengekai Building. What will happen to Soran and Houhou?

Houhou has no way to stop Ja Jongu’s attacks, and decides that she can’t win the way she’s fighting. She takes off her heels and uses her full power. Meanwhile, Soran negotiates with Saen so that if he can defeat her teleportation attacks she’ll let him go. She agrees, and launches her next attack. But her fist is stopped!
