Overview

Yako Katsuragi (桂木 弥子 Katsuragi Yako) is a 16-year-old high school girl and the very first character introduced in the manga. She meets Neuro when he appears and desecrates her father's shrine while promising to help solve the mystery of her father's death. This meeting quickly leads to a partnership: Yako becomes Neuro's cover, pretending to be an investigator while Neuro acts as her assistant. Her best friend is Kanae Kagohara, with whom she likes to spend time when she's not working on a case (at least until Neuro calls Yako to the office).

Personality

Yako has an insatiable appetite -with a cast iron stomach to match-, and a knack for understanding human psychology that occasionally provides Neuro with information he is unable to obtain, due to his unfamiliarity with how humans operate. Yako is even able to understand Neuro, to a degree, thanks to an amalgamation between the two aforementioned traits; she compares Neuro's opinion of food over that for oxygen to an experience that she had hunting for oysters under water.

Neuro enjoys abusing her and, as she has stated many times before, has forced her to go through a lot of humiliation and torture; but despite their sadistic-masochist relationship, Yako displays true affection and concern for Neuro, considering him to be one of the most important people close to her.

Although it is unknown if Neuro values Yako as much as she values him, he compliments her at times of success, albeit through a patronizing tone.

Abilities

Despite all that Yako goes through on a daily basis, she is relatively calm during high-stress situations, such as being kidnapped by X. While her time with Neuro has definitely been a factor in this, it is left to question if Yako had this trait before she became Neuro's front. It is also notable that Yako's abilities, and potential, as an actual detective is shown to be growing over the series, starting with the Aya Asia case, albiet slightly differently between both the anime and the manga.

Plot Overview

Yako appears at the beginning of the series at her father's funeral. She encounters Neuro for the first time after the funeral had ended, and Neuro forcefully adopts her as his cover so that he doesn't attract any attention when he goes around solving cases and consuming the mysteries. Yako and Neuro go to a cafe where they witness a murder, which would be their first case in the series. Neuro easily solves the case while pretending Yako had did all the deductions, and the murderer is arrested. Yako brings Neuro to her house again after this, and she asks Neuro to help her reveal the person who had killed her father. Neuro easily exposes Takeda Keitaro as the culprit, and after his arrest Neuro decides to continue working with Yako.

After the case at the Supreme S Neuro realises it would be easier for them to have an office as a hub so that he wouldn't have to search for Yako all the time. They go to a shady business office and meet Godai for the first time. Yako initially sees Godai as the most suspicious one, but after chatting with him she finds him the nicest one among his group. Neuro solves the case after ths, and they take over the office.

Shortly after opening for business, Yako and Neuro get their first customer, Aya Asia. After some snooping around, they manage to catch Aya's demented fan. Yako realises the fan couldn't have been behind the murders and tells Neuro, who immediately gives her some praise for at least knowing that fact. They later attend Aya's concert, where Neuro throws Yako onstage during Aya's performance to reveal Aya as the killer. After Neuro gives the deductions on how the crime was done, Aya asks Yako to personally tell how she could come to that conclusion. Yako reveals Aya had done the crimes out of the need of loneliness, and Aya willingly gives herself in, stating her satisfaction in having the honor of Yako solving her crime. Neuro praises Yako again after the case and tells her he hopes to see her improve further to assist him in his search for the greatest mystery.

After Aya's case, news on Phantom Thief X begin circulating the media. Around that time, a new client requests Yako and Neuro to help keep an eye on his son, who had been acting suspicious recently. They come across the son's secret hideout where he had been cruely killing local pets and compressing them into boxes just like Phantom Thief X. Yako and Neuro eventually corner him with the help of some police officers, and he reveals his motive for copying X. Neuro ignores him and reveals the real X however, and X is arrested by the police. X kills the officers in the car on the way to the police station however, and disguises himself as Yako to kill Neuro though Neuro isn't fooled and X escapes.
