Mekuru is a member of Future Foundation and is part of the 6th Division's Special Case Bureau as a special investigator.
Her alternative title is Sleeping Mekuru due to easily falling asleep in anytime and anywhere.
Mekuru has a small figure, with short light colored hair and yellow eyes. She wears a long jacket with black outlines that reaches her hips, a short skirt, puffy white socks and dark colored sneakers. Her jacket can be zipped all the way up, covering her face.
Much like Chiaki Nanami, Mekuru easily falls asleep anytime and anywhere, gaining the title "Sleeping Mekuru". Despite that, she shows high intelligence, being able to track down a culprit's location after she wakes up and after learning the case's information and going to sleep. People called her ability "Drowsing Deduction".
Mekuru also likes to be spoiled and carried, preferring to perform the Drowsing Deduction in Misaki Asano's arms instead of on the couch.
Prior to the Tragedy
Mekuru has resolved over 100 cases, all with great accuracy, despite her young age.
Chapter 2 - Symbiotic Hospital
Mekuru is sleeping in Takumi's arms and told Misaki that she and Takumi already knew each other for a long time before she fell asleep.
Chapter 3 - Bessatsu Shounen Zetsubou Magazine
Chapter 6 - Possibility of Despair
Chapter 7 - Pre-Wedding Mystery Tour
The two seem to have a close relationship, as Takumi is comfortable enough to carry her around and Mekuru gave him the nickname 'Hi-kun.' Misaki states that the two don't interact as simple co-workers, and have a deeper relationship.
Mekuru appears to be friends with Misaki. She decides to help Misaki out with her case, and offers to go as her partner when Takumi instead decides to go see Rei Shimizu. She refers to Misaki as "Asamin".
- "Carry me. I'll sleep better up there." (To Misaki Asano)
- Mekuru's title, Sleeping Mekuru, is a reference to Sleeping Kogoro, a character featured in the series Case Closed (known as Detective Conan in Japan).
