Ibara Saegusa/History

Early Years
Ibara was raised in an orphanage due to being abandoned by his birth parents at a young age. He doesn't remember their faces and has no desire to reunite with them. Ibara spend his early childhood mostly in the orphanage. He only started training as soldier not long after Yuzuru entered the Military Facility when the facility consider him to be old enough to train. Living the harsh life in the facility, He cherished his own life and vowed to himself that he doesn't want to die before he manages to find purpose in his life as well as something that he can cherish until the very end of his life. Therefore during his military days, Ibara only does his best just enough to stay alive but not stand out too much to avoid being sent to the battlefield. Due to being the only two boys of similar age in that facility, they end up forming quite an odd relationship with each other. Ibara implied to often tried to kill Yuzuru on multiple occasions as his attempt to overcome Yuzuru's skill. Yuzuru seems to be bothered by that attitude because Yuzuru always wanted them to get along but Ibara knew Yuzuru will eventually leave so he prefer to avoid getting too close to Yuzuru. Nevertheless, Yuzuru still did his best to be kind to Ibara, he often cook proper food for him and even make dessert only for him, in which it becomes the rare good memory for Ibara to remember. However, they later had a falling out due to Yuzuru returning back to being a butler for Tori.

Ibara was later discovered to have inherited part of the Godfather's property after his death. After he left the military camp, he spent his middle school days rebuilding all the affiliated companies that were left dying by the godfather from the ground up. He was surrounded by people who just worked with him for their own benefit. Thanks to that, Ibara he developed a deep mistrust of others and assumes that the kindness others give him always comes with an ulterior motive. The same reason also made him really strict with himself. Ibara doesn't usually allow himself to indulge in anything unnecessary that has no benefit for him. It is evident in Gang that Ibara dislikes the military camp due to his strong will to survive. This is why he prefers a life fighting wars with pens, words, and papers compared to his days assembling guns and grenades in the military camp.

War Era
Ibara appeared only briefly during the war era of Yumenosaki. Immediately following the subjugation match of fine against Wataru Hibiki of the Five Oddballs, Ibara approached Nagisa and Hiyori through their car window in the middle of the night in front of Yumenosaki's gates after their contracts were fulfilled with fine and made them an offer.

Ibara admitted that he had been wanting to scout them for a while, but the security around Nagisa and Hiyori was so tight that he couldn't speak with them until their contract with fine ended. Ibara extended the two an offer to join Cosmic Production that promised them a leadership position and the ability to begin at a management level within CosPro’s school system.

Last Year (Enstars! Era)
"See: Appears In"

Spring

During spring, a short time after the DDD, a security team was hired to respond to a terrorist threat made against Yumenosaki Academy. Ibara was well acquainted with this team; before the threat occurred, he had already infiltrated the security company and made their people willing to work for him. The terrorist threat was later found out to be their cover to sneak inside the school to gather beneficial information about the academy and its current students. This was part of the reason why Ibara knew all of the secrets that Yumenosaki's students had and the history of the school.

Summer Live

In the aftermath of Summer Live, Ibara was mentioned briefly by Jun as the Eden member who likes to set up his schemes via the internet. Hiyori also mentioned that Ibara was the one who provided the strategy that Eve executed against Trickstar in Summer Live.

Autumn Live

Ibara appears in Autumn Live. Introduced as a member of Adam, he guides Trickstar's members in enjoying the luxury Special Students in Shuuetsu have in order to gain their interest in joining the agency. He assigns Trickstar to Cosmic Production as the Special Temporary talent. Ibara turned the Revenge Match which Anzu and Trickstar proposed into the Autumn Live, a live where Shuuetsu's idols and its affiliated school's idols gathered. Trickstar just appeared as the guest. He planned to spy on them to learn about Trickstar from close up by giving them tablets used by the students and staff at Shuuetsu.

On the day of Autumn Live, Nagisa dismissed Ibara's script for their live as Nagisa realized that there is a hole in Ibara's plan. They manage to keep their appearance steady despite the problem.

Winter Live

In order to gain more fans from Yumenosaki territory, Ibara produced a Mall Live in a big mall around Yumenosaki, where he caught Makoto, who was scouting out Eden's work. He challenged Makoto to join the Mall Live. Mao, Izumi, and Ritsu, who were there by chance, decide to step in the challenge as well. At first, Ibara wanted to decline Izumi and Ritsu, but in the end he let them join the live as well.

It's revealed here that Ibara always acts as Eden's producer while handling other things as well. He says that he can't let other people produce Eden as Eden is the project he started by himself from the beginning.

Morning before the Winter Live start, Ibara tried to contact Subaru Akehoshi in order to set a deal with Trickstar and make Trickstar give up on the live. Ibara initiates this to avoid the possibility of Cosmic Production's bad executives exposing the scandal of Subaru's father, which unfortunately might expose the Godfather's relation to him too. But Subaru didn't take this call.

With the constant promotion as a unit, Eden starts to develop bonding with each other. During a break during Winter Live, Nagisa, Hiyori, and Jun expressed their feelings on wanting Ibara to rely on them more, but Ibara refused the help as he still holds strong to his word that he doesn't want to engage in any personal matters with them. Ibara ends up revealing his past to Eden for the first time, but until the very end still denies the other Eden members' will about them as a unit.

Trickstar manages to get into the top 8 in Winter Live. The bad executives of Cosmic Production end up releasing that scandal on the Winter Live stage's main screen when Trickstar was on the stage. This incident enrages Ibara; Jun states that Ibara appears to be angrier than he looks backstage. Ibara later decides to help expose the bad executives of Cosmic Production, hand in hand with the Tenshouin Conglomerate and Tomoe Foundation. (In the anime, Seiya Hidaka was the one who led the arrest.)

Saga

After the Winter Live scandal, most of the bad executives in Cosmic Production were purged, along with a lot of staff who were on the bad executives' sides, resulting in the agency falling into a terrible state. Ibara took this opportunity to revamp Cosmic Production as whole; with the help of Seiya Hidaka, he produced Lilith to participate in Saga to restore the sponsors' and public's faith in Cosmic Production. The same event also reveals that Ibara and Eichi Tenshouin already worked together to form the Ensemble Square Project, which by that time was more known as The Plan/ES Plan

Wonder Game

"Ibara is a major character in this event, check Wonder Game."

Current Year (Enstars!! Era)
"See: Appears In"

Ibara continues to revamp Cosmic Production, with him taking the position of Vice President in the beginning of his third year. He invested in the Information Bureau of Ensemble Square and become a member of it to support its activities and also control the information himself.

Outside his idol life and work in Cosmic Production, Ibara started a small Lesson Circle within the Star Harmony Dormitory, where he is known as the mentor who teaches difficult lessons in an enjoyable way. Ibara also keeps working on his business projects outside the entertainment world by expanding his businesses in other fields too. In Conquest, he invited the Cosmic Production staff to try out a new promotion from his ice cream shop.
