Part 1

 * The client is Rixia Mao, a performer with Arc en Ciel.
 * One week ago, Ilya Platiere, the troop's rising star, received a threat letter.
 * Ilya hates drama, so she didn't want to involve the police or bracers.
 * Based on Rixia's explanation, this isn't something that should be taken lightly. We agreed to investigate.
 * Let's first go to the theater and talk to Ilya. The Arc en Ciel theater is in the Entertainment District.
 * Arrived at Arc en Ciel. They're in the middle of a rehearsal, but we can head in through the main door.
 * Ilya gave us the letter. It demands the cancellation of their performance, and is signed by someone named Yin.
 * We asked if anyone bore a grudge against Ilya. The other day, Revache's Don Marconi rudely greeted her, and she slapped him.
 * Next, it may be dangerous, but we should pay a visit to Revache & Co.
 * Revache can be found in the Back Alley that connects the Entertainment District and Central Square.
 * Garcia reacted to seeing the name Yin.
 * Would the lawyer, Mr. Grimwood, know anything? He knows a lot about Revache. Let's also look for additional leads.
 * We stopped by Mr. Grimwood's office and told him what we know so far. He told us he doesn't know anything about this incident, but he did recognize the sender's name, Yin.
 * According to Calvardian legend, Yin is a skilled assassin that acts from the shadows.
 * Considering Garcia's reaction, it's possible Yin is connected to Heiyue.
 * Setting aside Yin's motive for threatening Ilya, let's investigate Yin's connection to Heiyue.
 * The Heiyue Trading, Ltd. is located in the Harbor District. Let's head there now.
 * We spoke to Branch Manager Cao Lee. We learned that not only does Yin exist, but that Yin also has a connection to Heiyue.
 * If Yin is targeting Ilya for a personal reason, this may not be something we can solve.
 * Detective Dudley from the First Investigative Division met us outside of the building. He had us tell him the state of our investigation thus far.
 * The First Division is to take over the case, and we are to return to our other duties.
 * Let's return to Arc en Ciel and report this to Ilya.
 * We discussed the situation with Ilya. She was accepting of it.
 * It's evening. Let's return to the SSS.
 * We reported what happened to Chief Sergei.
 * We may be able to continue the investigation a separate way.

Part 2

 * The First Division took over the investigation, but with the chief's support, we decided to investigate on our own.
 * We received an orbmail at the terminal this morning.
 * The orbmail was from Yin: 'Overcome this trial and face me. Only then will I grant you your mission.'
 * It was sent from the International Bank of Crossbell, not the police HQ.
 * Elie explained that the IBC's CEO, Mr. Dieter Crois, is her friend's father, and he might allow us to investigate the IBC building.
 * Let's head to the IBC. We should also check for support requests before we go.
 * Arrived at the IBC. Let's ask to see Mr. Crois at the desk.
 * Mr. Crois agreed to see us. Let's go to the top floor using the elevator.
 * With the IBC's security, it is unlikely that someone could break in. That leaves open the possibility of hacking.
 * Mr. Crois has granted us permission to enter the terminal room. His daughter, Mariabell, will take us there.
 * The terminal room is on B5. Let's use the elevator.
 * The terminal log indicates it was being remotely accessed when the orbmail was sent.
 * Some logs were deleted, but Tio and the researchers were able to restore them and identify the source terminal.
 * Control Terminal 8 is located in Geofront B Sector. The B Sector is a separate section from the A Sector that we already explored. It covers the northwest area of the city.
 * Let's go to City Hall and see if we can borrow the key.
 * Borrowed the B Sector key from City Hall. The access door is located near the canal in the Residential District.
 * Entered Geofront B Sector. Let's head to Control Terminal 8.
 * In the terminal room, we found Jona, who calls himself an informant. He gave us a card, saying it was written by Yin.
 * The card says: 'The door has been opened. I summon you to challenge me at the Tower of the Stars and hear my wish.'
 * Jona has seen Yin before, but his identity has always been hidden. He wears black, and his face is always shrouded by a mask.
 * The Tower of the Stars probably refers to Stargazer's Tower, which can be reached from Ursula Road. We have no choice but to check it out.
 * We ran into Sergeant Major Seeker at the tower's entrance. While on patrol, she had found the CGF barricade damaged and was there to investigate.
 * We gave her a summary of what's happened so far. She will accompany us during our investigation of the tower.
 * Time to explore Stargazer's Tower, said to have been built during the Middle Ages. This won't be easy. In addition to the basic elements of earth, water, fire, and wind, the higher elements of time, space, and mirage are active here.
 * The monsters wandering around look quite unfamiliar. Was this part of Yin's trap? Let's explore cautiously.
 * Met Yin on the tower's top floor. After testing our mettle in combat, he was willing to answer our questions.
 * As we suspected, the threat letter was not written by Yin. Someone else must have been responsible. Yin requested that we seek out the real culprit.
 * In line with Yin's request, we should pursue that criminal. We decided we would patrol Arc en Ciel's theater during their opening day and the day of their private performance.
 * Yin took off. We pursued him upstairs to the rooftop, but to our surprise, he must have jumped off the tower and gotten away.
 * On the day of the private performance, I entrusted the perimeter patrol to Randy, Tio, and Zeit, while Elie and I patrolled indoors.
 * Let's comb the theater by speaking to the staff and looking for anything out of the ordinary.
 * Act 1 is over, and Act 2 is about to start. Let's patrol again.
 * Act 2 is over, and Act 3 is about to start. The performance is reaching its climax. Let's stay on guard.
 * When the final act was about to begin, we received a report from Manager Balsamo of a suspicious guest! The person wasn't on the invitee list, and appears to have snuck in to monitor the section S seats.
 * The suspicious guest was Grace. We asked her why she snuck in, and she told us about sinister rumors surrounding Ernest, Mayor MacDowell's secretary.
 * Along with what we already knew, it makes sense now. We rushed over to the VIP seats to find Ernest attacking the mayor!
 * He managed to escape, but he was captured by Tio, Randy, and Zeit outside.
