## Volume 1

**Chapter 2: Yes, She’s The Self-Proclaimed Cutest Idol**

Yui introduces herself quite abruptly to Kimihiko, boldly proclaiming herself as Yui Saikawa, the idol singer. Yui is described as “a singing, dancing middle school idol…” Yui then abruptly asks Kimihiko to stop the theft of her sapphire that is worth three billion yen. Kimihiko is confused by this, but later Nagisa steps in to accept the request.

**Chapter 2: A simple job: Protect a three-billion-yen family treasure**

Yui invites them to her mansion, and after a comedic interaction, she elaborates on the job she has for Nagisa and Kimihiko. She states that the sapphire is sure to be the family heirloom of hers, the Miracle Sapphire. Kimihiko is reluctant to accept this request, but Nagisa convinces him to take the offer anyway. Yui also elaborates that she tried to get the police involved, but they wouldn’t accept due to “lack of evidence,” despite the note she has from the soon-to-be culprits, which gives the specific details of their crime. Kimihiko is offered to be introduced to the vault room, and this is when he asks Yui why her parents aren’t requesting this of them, but she states that her parents are deceased as of three years ago.

**Chapter 2: That’s “Yui-nya Quality”**

A few days after the previous events, Yui is having a rehearsal, in which Kimihiko and Nagisa are attending. Kimihiko has become a fanboy for Yui, but this is revealed to be an act later on. This is where Kimihiko gains valuable information, according to him.

**Chapter 2: Sunday showdown**

Sunday rolls around and it is the day that the Miracle Sapphire is supposed to be stolen. Kimihiko and Nagisa arrive at Yui’s concert with the help of Bat, and search for the person who is going to steal the sapphire. Kimihiko made a discovery over the time he was researching Yui, and that was her eye, which resembled a sapphire.

**Chapter 2: Star Phantasm**

The star song is supposed to play, which is where Yui reveals her big secret. Kimihiko and Nagisa have lost communication in the crowd, and it has proven to be extremely difficult to locate the person who is after Yui in the bright lights. Though Bat assists Kimihiko, and they locate the man who is going to shoot Yui with a crossbow, but Kimihiko saves Yui just in time.

**Chapter 2: Thus spoke the super idol**

They return to her dressing room and Yui apologizes for not telling them the full story. Yui explains that she got her left eye from her parents as a gift, as she was previously blind in her left eye from birth. She cherishes the gift due to it being from her parents, and that is why she didn’t really elaborate on it. Everything seems resolved and forgiven, but then Kimihiko calls Yui out on attempting to kill them by mentioning the “penalty” she will have for failing to do so.

**Chapter 2: What that eye sees**

Yui is shocked, and denies working with the criminals at first, but it is confirmed once Kimihiko receives a call from Fuubi. Fuubi states that a bomb was planted in Yui’s vault, and Kimi and Nagisa would have died if they were there. Fuubi also states that the police were never notified of the threat that was placed on Yui, contradicting what Yui said previously. Kimihiko then calls out Yui’s eye, claiming that it can see through objects by saying, “Tell me, right now, what can you see?”

**Chapter 2: More than any idol**

Yui answers by pointing out the gun in Kimihino’s bag, and this starts a stand down. Yui begins getting hostile with Kimihiko, and it doesn’t seem anything will be good in this situation. Kimihiko is trying to negotiate with Yui about how her enemy isn’t them, but rather it is SPES, and they should be working together. Yui is in a state of pure defensiveness, and isn’t listening to Kimihiko, making it all seem pointless to negotiate. Luckily, Nagisa steps in and offers a beach trip with Yui, very unexpectedly. Nagisa then offers Kimihiko and her friendship to Yui, which breaks Yui’s previously unwavering stance. Yui feels guilt and shame for trying to kill them, but Nagisa comforts her. Kimihiko then offers to become allies, as they have the same enemy; SPES. Saikawa then emotionally accepts their offer.

**Chapter 2: Because you said “Let’s go to the beach”**

A little over a week later, Yui brings Kimihiko and Nagisa on a cruise ship headed to the Aegean. She considers this an apology, and a fun trip with her newly founded friends.

**Chapter 3: Yesterday’s enemy is today’s enemy, too**

When the confrontation of Charlotte to Kimi is occurring, Yui is completely silent, and doesn’t interfere at all. Yui only says something as soon as Charlotte leaves, and that would be an apology to Kimi for bringing him to a place where he had to argue with someone. After this brief interaction, Yui takes Nagisa to the water slides and pool area, while Kimi searches for Siesta’s legacy.

**Chapter 3: The worst happens**

Once Kimi awakens, he is being held by Yui, which is because he had to stay in her room, as Charlotte was occupying his. It is then brought to the attention of all the passengers that Nagisa Natsunagi is being held captive somewhere, and to get her back, they must bring the captor Siesta’s legacy. This causes Kimi and Yui to be quite concerned for Nagisa, and they immediately begin to search the boat.

**Chapter 3: How to use a three-billion-yen family treasure**

Yui assists Kimi by using her sapphire eye to see through everything, but this is to no avail, as they cannot locate Nagisa or the legacy. Kimi is panicking, but soon calms down from guilt after understanding that when Yui uses her eye too much, it becomes strained. Yui soothes him with words, and after a comedic interaction between them, they talk about how Kimi is being extremely apologetic and how he doesn’t understand anything. Yui says she was once the same way, saying this to Kimi, “Like you, I couldn’t live on my own, either.” She then elaborates on how it was her parents for her, but it was Siesta for him. She then relates Nagisa and Kimi to her, being that they are incomplete people. She then decides to be Kimi’s assistant; she is declared the assistant’s assistant.

**Chapter 3: Light in the midst of hope**

Yui is driving a speedboat to where Kimi is at so she can save Nagisa, so Kimi can fight Chameleon without the worry of Nagisa dying. She successfully does so, then leaves.
