==Biography==
===Bloody Field Trip Case===
Elmer is originally from America. He transferred to BLUE three days before the Bloody Field Trip Case.
On his first day, Elmer attracted a crowd because not many students transfer to BLUE. They asked what he did to get into the school; Elmer avoided the question and instead inquired about Ron Kamonohashi. After finding out that he was BLUE's top student, Elmer went to talk to him, and although Ron told him to leave him alone, Elmer was determined to become Ron's friend.
The day before the Bloody Field Trip, Elmer hurt his shoulder on a shelf when he fell off a ladder in the library. Ron found him and treated his wound. When Elmer asked him if they were friends, Ron left the choice to him, and Elmer decided they were friends and partners. Ron, however, cannot remember this event; by his account, he spent the majority of his time before the training exercise alone in a basement room. 
After the Bloody Field Trip, Elmer disguised himself as a police officer to gain access to the case's file. He also spent the next years trying to find Ron.
===Coin and Carving Murders Case===
Years later, Elmer manages to track down Ron at his home right after he got involved in a hit-and-run. He falls into the apartment after Ron opens the door, and because Elmer overheard Ron and Totomaru Isshiki's conversation about Ron's previous friendless state, he declares himself as Ron's only friend at BLUE before he loses consciousness.
===Obon Dance Murder Case===
Subsequently, Toto and Ron take Elmer to a hospital. While Ron and Toto discuss him, Elmer joins them and introduces himself. He claims that although he had transferred to BLUE only three days before the Bloody Field Trip Case, he and Ron became good friends, and Ron even accepted Elmer as his investigative partner. Further, Elmer spent the last five years tracking down Ron because he vanished after his expulsion.
Still suspicious, Ron decides to keep Elmer close for now so that he and Toto can gauge him properly. They show him around and eventually find an Obon festival and agree to attend it. There, they run into Chicory who is gathering material on summer festivals. Because Chicory calls Toto "Officer Isshiki," Hiiragi, the manager of the famous singer Nana Haruno, approaches him and asks for a favor: 15 years ago, when Haruno performed at this festival as well, she received a death threat. Though she has received no such note this time, the culprit has likely been released from prison by now, and Hiiragi fears that they might still return for revenge. Elmer, Toto, Ron, and Chicory agree to help and watch the venue.
During Haruno's performance, Elmer impresses Ron by swiftly gathering information on the members of Haruno's band. In his attempt to prove not to "lose" against Elmer and prove himself as Ron's investigative partner, Totomaru embarrassingly mistakes fireworks and a laser light gun for a gunshot and a real weapon. A moment later, all lights go out and a scream rings through the loudspeakers. Elmer, Totomaru, and Ron hurry to the stage and discover that Haruno was stabbed.
Haruno, in critical condition, is rushed to a hospital, and Hiiragi accompanies her, whereas Elmer and the others stay behind and investigate the case. The murder weapon was stolen from a takoyaki booth, and a man from the neighborhood association turned off the lights for 30 seconds at 6:15 p.m. because he received a message from Hiiragi. However, they find her phone in the trash, and Hiiragi testifies that she lost her phone before Haruno's performance.
Afterward, Elmer and the others speak to the musicians that were on stage with Haruno. Each of them—Tsutsui, Kimura, and Tateishi—plays an instrument that requires both hands. Thus, none of them could have stabbed Haruno without stopping to play, and the music continued throughout the attempted murder. They also did not notice anyone coming on stage during the blackout.
Elmer, Ron, Toto, and Chicory then discuss the case. Elmer believes the culprit from 15 years ago might be one of the musicians, pretending to be a local. Chicory mentions that person also used to gift poisoned chocolate to other idols, and while she checks the previous case again, Toto calls Hiiragi for further information: Back then, a box cutter blade and a bullet were sent to the office of Haruno's agency back then. The bullet also reminds Hiiragi of the earlier commotion. Chicory returns and announces that the old culprit is already dead.
Determined to identify the new culprit, Totomaru attempts to play the musicians' instruments one-handedly and, by chance, discovers that one of Haruno's false nails is lodged deep inside the stage's paving stones. Ron then solves the case and thanks Toto for helping him. Elmer is rather amused and surprised to see their interaction, noting how different Ron has become.
Right afterward, Toto receives a call from Haruno's hospital that she regained consciousness, and Ron instructs the hospital to get Haruno a bodyguard as the culprit will try to finish their business.
Elmer and the others hurry to the hospital and can stop Hiiragi just in time. She was hiding under the stage during Haruno's performance. The blackout was meant for a costume change, but when the lights went out, Hiiragi stabbed Haruno instead. Hiiragi gave herself away when she mentioned the gun commotion: If she had been in front of the stage as she claimed, she would have known that Totomaru had made a mistake and there had never been a gun. Furthermore, Hiiragi asked for Toto's help protecting Haruno because she had not planned to kill Haruno. However, when Haruno mentioned that she had given away the candy she received back then to children, Hiiragi decided to murder her.
Hiiragi admits that she wants to kill Haruno because she was one of the children who got candy. She gave hers to her bedridden mother; she died not long afterward, and Hiiragi believes that the candy must have been poisoned. Haruno woke up in the meantime and now reveals that she did not give Hiiragi the candy that a fan gave her: When Hiiragi came to Haruno, she had already run out of candy and given her other sweets as a substitute. Shocked, Hiiragi apologizes to Haruno.
Thereafter, Elmer, Ron, and Totomaru head home, and Elmer says he will stay in Japan for a while before they part ways. Elsewhere, Elmer then briefs someone about his time with Ron.
