## Synopsis

### Volume 4

As Ai is running away from home, she meets Teru Momijiyama and Iko Koishikawa going out together. Since they were going the same way, they leave together, to which Ai is very grateful for her help, introducing herself as well. However, as she doesn't seem to know many of the things they were talking about, they decide to take her along for sightseeing. After that, Iko questions her about whether her parents wouldn't be worried if she were to go back home late, but as she is about to answer, a purse snatcher has just robbed an old lady.

Ai notices Teru is about to do something and stops her from doing so, knocking off the snatcher by herself. The police is called and she feels fatigued, but refuses to go to the hospital, revealing to them she was actually running away from home.

### Volume 5

Ai explains to them that she was being followed, and her parents nor the police believed her, thus she ran away from home. She asks them to accompany them a while longer because she was lost, to which they agree. Teru Momijiyama is curious about her swordsmanship skills, and Ai tells them that comes from a clan of shinobis, but they seem skeptical by this information. A boy comes from the sky after Ai, so she fends him off with a sword skill, running away with Teru and Iko to a nearby temple.

There, she explains to them that that boy was the one following her, and even though she was again fatigued, she says they should get going or he would find them again. Ai steps on false, however, and falls down the stairs of the temple. She is fortunately saved by that same boy, Tokimaru, who is there to take Ai back to their village. They get on top of a torii and Ai argue with him to leave her alone.

When they get down, she tells the other two that she wants to be free, and also explains to them what shinobi are and what they do. As Tokimaru is unwilling to leave, Ai introduces her sword, Purity, to them, and Teru analyzes it briefly. When Ai takes it back, she reveals that the sword can read other people's Hearts and states some things about Teru, as well as she is the Hero she has been looking for.

Ai shows them a scar in her chest, a wound she received when she was young that made her heart weak. She tells Teru that she has been feeling a dark Heart, and asks her help to erase that evil. Tokimaru is immediately against it, questioning whether she even had somewhere to stay. Ai decides on the spot she would stay at Teru's house. As Iko had to go to make dinner for her brother, Ai arrives at Teru's house with Teru herself and Tokimaru, to whom she demands to stay outside.

Ai starts to take a bath and even invites Teru over, but she shyly refuses. When she finishes, she offers herself to make dinner, and Teru is surprised by how good it tastes. She explains to her that a blade can be a deadly weapon or an useful tool depending on which emotions one puts on the blade. Even though it appears as if Ai doesn't care for Tokimaru, she still goes out of her way to give him some food, too, but also asks him to leave.

When she thinks that Tokimaru is hitting the doorbell, it's actually Iko who came back to have a sleepover with them. After playing some games for a while, Ai decides to be truly honest with Teru and Iko, and tells them the ones following her are actually a group named Amarariruku. As they seem to be familiar with them, she explains the one following her is "the other her". To this information, Teru immediately reports to Unilord.

In the next morning, Ai wakes Teru up and brings her to a isolated place so they can know each other better. She is amazed by her Hero form, and reveals to them that she can transform as well. Ai suggests that they play a game of rock skipping, explaining that, in her village, they would do that to train shuriken throwing skill. Shy and Iko, do not know how to replicate her skills, however. While they're thinking, Ai leaves to search for Tokimaru.

She finds him at the top of a tree, observing the place, and tells him what she was doing with Shy and Iko. They briefly reminiscence over the times where they would train together, that until Ai finally notices he is half-naked. Tokimaru tells her that he was washing his clothes by the river before they arrived, but as he didn't take off his scarf, Ai gets curious. He says that he doesn't want to lose the scarf because it's very important to him, and Ai tries to provoke him by saying that it was given to him by a girl he likes. Tokimaru bluntly tells her that it was Ai herself who gave it to him. Ai doesn't seem to remember it, however.

He brushes it off and tells her he is worried about the path that she chose, but she tells him only her can rescue her soul. At last, she gets up and extends her hand towards him so he can accompany her. She comes back to Shy and Iko alone, and when she notices that neither of them could discover how she threw the rock into the tree, she explains that rocks also have a Heart. Using her advice, Shy is able to do the same.

They play for a while, and after that, Iko offers some tea to Ai, to which she accepts. She then asks her who she got there and Ai explains that she learned how to use the train, had to switch many of them until she arrived in Tokyo and got lost. She prefers the calming nature of that city. Suddenly, Purity seems uneasy, and the Shy receives a message from N. Villio that part of Tokyo was covered in a mysterious dark void, surprising her.

Shy immediately is called to the Heroes' Hideout to discuss on what to. However, Ai is the only one to know how to infiltrate that dark dome, so she infiltrates the hideout with Iko to offer her assistance to Shy. She convices Shy as Purity told her how to infiltrate the dome, thus she should be going with them. Unilord sees no problem with this and allows her to come along. Shy recruits Spirit, Mian Long and Lady Black for the Infiltration Team and they head out to Tokyo.

With Purity, Ai is able to breakthrough the dome. The team infiltrates it, and even though Ai is not a Hero, she seems completely fine, even if other civilians, found by Spirit, are in a catatonic state. As Lady Black inspects them, they are attacked by Doki, who rushes after Ai, but she is protected by Shy and Mian Long, and they prepare to battle.

### Volume 6

Doki introduces himself to the heroes, and wants to take Ai to the top of the tower as per Utsuro's requests. Lady Black is able to unexpectedly convince him to take them all along, and Shy asks him about the civilians. He tells them that Utsuro has been draining their hearts, and that they would only have about an hour before they become "lost". Due to a comment regarding his taste for cute things made by Shy, he becomes angry again and attacks them.

Mian Long counterattacks and paralyzes Doki, then tells Shy and the others to go on ahead while he fights the Amarariruku alone. Even though Lady Black initially protests to this, they eventually follow Shy's lead and leave Mian Long behind.
