In a Perth restaurant, Olivier drank the classical wine "Gran Chalina" that was bid by the mayor and was called the "Illusion Classic". The person in charge of the restaurant called the soldiers and put him in jail.

At this time, he also met Estelle and others who were arrested by General Morgan. Olivier told them about his "extraordinary experience" and was treated uncooperatively by everyone.

After being released from prison, Olivier followed Estelle to the mayor's house and learned that a large-scale robbery had occurred in the south neighborhood of Perth. Olivier also joined the investigation team.

During the investigation, he met the colonel and after learning the colonel's name, Olivier seemed to notice and remember something, but he did not want to tell everyone what he was thinking.

After getting clues from the shores of Lake Valyria, Olivier accompanied Estelle and others to Chuanchan Pavilion, but was made drunk by Sheila because Sheila did not want Olivier to participate.

But Olivier still woke up and caught up with Estelle and others, and stopped them from fighting the sky pirates, boldly suggesting that he sneak into the airship and follow them to the secret base.

After solving the incident involving the Sky Pirate Group, Olivier left.

On the ship, Olivier spoke to an unknown person and mentioned the sky pirate incident, the Capua family, and Cassius.

After calming down, the people retreated, leaving only Olivier, Estelle and others.

Olivier was narcissistic as always and asked Dorothy to take pictures, while Estelle and others left speechlessly.

Since then, Olivier has joined Estelle to help them investigate Luann's White Shadow incident.

After investigating that Bai Ying is one of the executors of the Body-Eating Snake Organization - the Phantom Thief Lubululan, when faced with Lubululan's aesthetics, Olivier said that Lubululan's aesthetics are simply petty.

Levi then discussed and argued with him about the true meaning of beauty, which impressed Lubululan deeply.

After solving the White Shadow incident, Olivier left.

When the royal capital fell into chaos, friction arose between Liber and the Erebonian Empire over the floating city above Liber. At this time, the empire sent Olivier and Koros, sent by Liber, to negotiate.

At this time, Olivier's true identity was revealed, and he turned out to be the prince of the empire - Olivier Lazer Arnall.

When Olivier entertained the students of Class VII, he encouraged Rean and others to become the light that transcends all kinds of barriers from different opposing positions.

Olivier secretly leads the plan to build a high-speed cruiser, hoping to suppress the domestic confrontation by stopping the ambitions of the Iron-blooded Chancellor Gillias Osborn and becoming a third force different from the neighboring armies and the Imperial Army.

"The Legend of Heroes: Trails of Cold Steel II" When Rean was invited by the leader of the noble faction, Duke Kane, to Patanguai in the noble alliance, Olivier organized a rescue operation.

When Rean's ghost power was gone and he was unable to deal with many masters, Olivier appeared with his friends on the red-winged Karejas, making the already tense and explosive atmosphere slightly more relaxed.
