Mikami is a recurring character in Logicalism categorized under the Kisetsu no section.


Mikami has green hair and blue eyes. He's often seen wearing a green hat with cat ears and two buttons sewn in; he also wears a matching green suit with a brown tie and gloves. When Mikami took in Shirakawa Haruka, he wasn't comfortable and couldn't look at him in the eyes; and so he decided to wear the hat hoping he wouldn't look as scary.

Most of the time, Mikami is seen wearing a suit as his costume.


Mikami has a hobby of collecting hats, likes very sweet foods, and his signature move is standing out. Currently, Mikami works as a private detective; with Haruka and Miyashita Hiro as his assistants. After the incident of the fire, he took in Haruka. Two years afterwards, he took in Hiro after the Aoi family suicide case (in the finale of Yuuhi Iro ni Somaru Nazotoki)

During his high school days, he attended Tsukimizaka School and is a member of the mystery club. Mikami's good friends with Yamabuki Ayato, and has a crush on Akatsuki Sakurako; who's also a part of the mystery club. He's said to hate Akatsuki Kanau after the events of "Aka to Hai", and can be said rivals. He's also a friend of Shimada Shimako, whom, like Sakurako, also a part of the mystery club.

He doesn't like his real name Himeno (姫野) Mikami (ミカミ) , and now goes by the name “Mikami” (深神).


Role in "Yuuhi Iro ni Somaru Nazotoki"Edit

In "Yuuhi Iro ni Somaru Nazotoki", Mikami was hired to investigate a case by Aoi Chiyo. A painting was stolen and on the same day, Aoi Kazuya, Chiyo's husband, committed suicide. Mikami investigated their house and met Aoi Moyuno, their daughter.

During his investigation, he ran into Shimako who was an investigator of the case. Mikami and Shimako later both had a talk in a cafe where they tried to catch up with things. She asked if she'd been keeping in touch with Sakurako, and that he replied he does so from time to time. Sakurako said that Kanau died not too long ago, and Shimako was rather surprised to hear that.

As the case came to a close, Chiyo and Hiro were murdered. The only survivor was Moyuno. Mikami took in Moyuno, with the condition being to live on as "Miyashita Hiro" and abandon the name "Aoi Moyuno". He requested Shimako to falsify the identity of the corpse, so that it'll later be known as the "Aoi family suicide incident".

Role in "Umi wa Sono Nazotoki wo Nozomu no ka?"Edit

Mikami plays an important part of the story and can be considered a main character in "Umi wa Sono Nazotoki wo Nozomu no ka?". In the story, Mikami received a letter saying a crime will occur on the Yotsuba cruise ship. He attended the cruise with Haruka, and various crimes occurred. A man was poisoned (Murasaki Kojiro) and two people fell to the ocean (Sato Keisuke and Takamatsu Mikaze).

By the end of the story, Mikami was able to find the person who sent him the letter (Kurono Miyako). It was rather impossible for Miyako to be able to carry on the murders all by herself, so Mikami suspected she had an accomplice; which was Keisuke, who Miyako herself claimed 'fell' to the ocean.

Role in "Kimi Hitori"Edit

In "Kimi Hitori" Nishimori Sota asked Mikami's help to find a girl named 'Murasaki Mizuki'. He answered saying she didn't exist and he couldn't find information of her anywhere, however he only lied because he was asked by Hiro not to say anything of it (later on, the information of Mizuki was found by Haruka).

Role in "Sakasama no Kami-sama"Edit

Rokurogi Reika came to Mikami's office one day hoping he could answer more questions about the Yotsuba cruise ship case. Before Reika could do so however, Mikami received a call from Hiro saying someone had planted bombs around her school, Tsukimizaka Academy (by Washimura Sumito). He contacted Shimako and went there as soon as possible.

Sumito asked one of the students who were barricaded in the event to find the data of "Himeno Mikami", a former student of the school there; for reasons unrevealed until later in the climax.

Role in "Nazokake" (Novel)Edit

Like "Umi wa Sono Nazotoki wo Nozomu no ka?", Mikami received a letter saying a crime will occur in the Yotsuba cruise ship. He came with Shirohane Len, and was accompanied by Yuno Shinpei.

After the condo fire, Mikami passed on Haruka's message, saying, "he didn't want to come home" to his parents; though they were understanding, of course they'd forgive their own son.

Haruka changed the subject and asked who the arsonist was. He said he'll kill whoever set the fire. Mikami explained that if Haruka wasn't able to kill someone like him, it'd be really hard for him to kill the actual 'culprit'. He would tell him what he wanted to know, and Mikami would look after Haruka as well.

It had been a while after Haruka moved in with Mikami, and he still couldn't look at him in the eye. Mikami decided to wear a hat, saying he wasn't scary to look at anymore and that Haruka should call him "Papa". It turns out Haruka just didn't like looking at people's eyes in general.

Ayato asked Mikami to go see a movie one day, and he was really excited to hear that; saying it'd be like a "date". As Sakurako teased Ayato, Shimako commented people who don't understand what they're doing are the worst.

When the two reached the cinema, Mikami immediately picked a movie and Ayato went along with it. When they were watching, Mikami teased him, saying Ayato's reaction was a bit too much. Ayato made an analysis of the background music instead and Mikami wondered if he'd teased him too much.

By the end of the movie Mikami gave Ayato the soundtrack to the movie "Ibaliger", saying he knew that's the reason he invited him to go see a movie. The two said their goodbyes, but Mikami is later seen with Sakurako together.

Mikami was irritated of Kanau who kept on being close to Sakurako, so he challenged a game of cards with him one day; as Shimako and Sakurako watches. Although Mikami was able to memorize some of the cards, Shimako switched their places knowing he'd do just that, and Mikami lost the game. Kanau on the other hand was able to remember the scratches and dents on the cards and won the first round of the game.
