Detectives These Days Are Crazy! (Japanese: まったく最近の探偵ときたら, Hepburn: Mattaku Saikin no Tantei Tokitara; lit. 'Detectives These Days, Really') is a Japanese manga series written and illustrated by Masakuni Igarashi.

Plot

[edit]

About 20 years ago, Keiichiro Nagumo was an ace detective in Japan despite being in high school. No case was too tough for him to solve. However, at 35 years old, his age is catching up with him. Nagumo no longer has the youthful energy or fame from his high school days. Suffering from aching hips and back issues, on top of growing increasingly jaded, his private eye office is struggling to attract clients and making it hard to afford rent and food. One day, an excitable high school girl named Mashiro Nakanishi appears at his doorstep and wants to be his apprentice, which he refuses. After she helps him finish a case, Nagumo reluctantly hires her.

Characters

[edit]
Keiichiro Nagumo (名雲 桂一郎, Nagumo Keiichirō)
Voiced by: Junichi Suwabe (voice comic, anime)[2][3]
A former genius detective as a high school boy, but now a washed up 35-year-old man running a failing private detective agency who struggles with modern technology and cultural references. Even so, he indirectly inspired a newer generation of detectives and assistants with his former exploits.
Mashiro Nakanishi (中西 真白, Nakanishi Mashiro)
Voiced by: Kana Hanazawa (voice comic, anime)[2][3]
A bubbly and excitable high school girl who looks up to Nagumo, often uses brute force to complete any task she is given. She can somehow procure any equipment in an instant, from a self-inflating stunt mat to a loaded flamethrower, hidden in her student uniform.
Cerberus (ケルベロス, Keruberosu)
Voiced by: Chado Horii (voice comic, anime)[2][4]
A stray cat that was captured by Nagumo for a client, only to find out the cat was not the same as the client's. Due to the client's refusal to take it with her, Mashiro decided to keep the cat in the office and named it Cerberus.
Taro Nezu (根津 太郎, Nezu Tarō)
Voiced by: Kengo Kawanishi (voice comic, anime)[2][5]
A low-level Yakuza who quits his job after Mashiro torches his group's office with a flamethrower. He soon joins the Nagumo Detective Agency, running errands for them.
Yuu Asunaro (翌檜 ユウ, Asunaro Yū)
Voiced by: Tomohiro Yamaguchi (anime)[6]
Another fan of Nagumo's younger days who wants to become his apprentice, even though he has his own detective work and adoring female fanbase. Unlike Nagumo, he wears more traditional Japanese clothing. A master of lockpicking and other security tasks that require finesse, he immediately becomes Mashiro's biggest rival.
Hana Kazamaki (風巻 ハナ, Kazamaki Hana)
Voiced by: Aya Hirano (anime)[6]
Yuu's assistant who seems to barely tolerate his antics. She was given the job after not being intimidated like the rest of his fangirls when Yuu deliberately made himself appear ugly during an audition to be his assistant.
Azuha Hoshino (星野アズハ, Hoshino Azuha)
Voiced by: Fairouz Ai (anime)[5]
College dropout and self-proclaimed Star Agent who invents several spy gadgets and custom drugs. Her office is on the floor below that of the Nagumo Detective Agency.
Fū-chan (風ちゃん)
Voiced by: Misaki Watada (anime)[5]
The daughter of Detective Mimasaka who was inspired by her father's stories on the job, and now dreams of becoming "Phantom Thief Beaver," constantly stealing little items from Nagumo's office to prove her skills and annoying Mashiro with comments about her appearance.
Soya Mimasaka (美馬坂総也, Mimasaka Sōya)
Voiced by: Yasuyuki Kase (anime)[5]
Nagumo's former classmate. Similar to Nagumo, he was a detective in his high school days who turned 35 years old, and struggles with modern-day technology. Unlike Nagumo, he joined the TMPD after graduation, and now works as a civil servant instead of a private eye. He claims to know Mashiro's "real identity" and the reason behind Nagumo's downfall from fame.
Coach (コーチ, Kōchi)
Voiced by: Hajime Iijima (anime)[5]
A large black man whose real name is unknown, but often featured in Mashiro's flashbacks as having trained her to fight.

1"Former Great Detective Nagumo Keiichiro"
Transliteration: "Moto Meitantei Nagumo Keiichirō" (Japanese: 元名探偵 名雲桂一郎)		Rion Kujō [ja]Rintarō IkedaRion KujōJuly 1, 2025 (2025-07-01)
"Mashiro's Pest Extermination"
Transliteration: "Mashiro no Gaichū Taiji" (Japanese: 真白の害虫退治)

Private Detective Keiichiro Nagumo tries to track down a suspected cheating wife when his back flares in pain. Before he can make it out the door, a hyperactive high school girl shows up unannounced and requests to be his assistant. He refuses and follows his target to a nearby café, when the same girl shows up again, and helps him complete the job by pretending to be his "age gap" girlfriend despite his loud protestations. After getting photographic proof of the cheating wife for the client, Nagumo reluctantly lets the girl stay on as an unpaid apprentice, and she reveals her name as Mashiro.

After taking on a stray cat as their unofficial mascot, Nagumo tasks Mashiro with another client's request to exterminate a bees' nest. However, a lack of clarity on the address leads Mashiro to the office of a yakuza group, but she proceeds to destroy it anyway. In the process, she scares a low-level member named Nezu to quit before she kills him, and Nezu repays her by joining Nagumo's office.
2"With Ghosts, Go for the Knees"
Transliteration: "Obake wa Hiza o Nerae" (Japanese: オバケは膝を狙え)		Isoroku KogaRintarō IkedaIsoroku KogaJuly 8, 2025 (2025-07-08)

Transliteration: "Shin-han'nin o Sagase!!" (Japanese: 真犯人を探せ!!)
"Three Minutes Until Mashiro Explodes"
Transliteration: "Mashiro Bakuhatsu San-pun-mae" (Japanese: 真白爆発３分前)

Mashiro's classmate Hayashida visits the office with a request to investigate a spooky ghost that appears near his home. Mashiro has a deep fear of ghosts, but Nagumo convinces her to investigate with him anyway. After a week of attempts to catch the ghost turn up nothing, Nagumo realizes that Hayashida recorded himself disguised as a ghost and played the clip each time Mashiro came over because he wanted an excuse to talk to her, revealing he has a crush on her. However, after Hayashida confesses, Mashiro returns with a real captured ghost.

Nagumo is held by the Tokyo MPD under suspicion of being an underwear thief, where his former classmate, Soya Mimasaka, is the one interrogating him. However, the person caught on camera stealing underwear looks a lot like Nagumo, so Mimasaka refuses to release him until Mashiro and Nezu set a trap to catch the real thief and bring him to the station.

A captured suspect called "Knit Man" reveals he planted a bomb in a nearby parking garage. Mashiro attempts to disarm the bomb, but is running out of time. As a result, she opts to kick it inside an abandoned baseball park. Unbeknownst to Mashiro, Nezu is there taking pictures when the bomb explodes.
3"Great Detective Asunaro"
Transliteration: "Meitantei Asunaro" (Japanese: 名探偵アスナロ)		Kōji AritomiRintarō IkedaKatsuyuki Kodera [ja]July 15, 2025 (2025-07-15)
"The Ones Don't Realize They're Stalkers are the Most Dangerous"
Transliteration: "Sutōkā no Jikaku ga nai Yatsu ga Ichi-ban Yabai" (Japanese: ストーカの自覚がない奴が一番ヤバい)

Nagumo laments the fact that he has no money to pay for his office's rent when Yuu Asunaro, himself a young private detective inspired by Nagumo's former exploits, breaks into his office and offers to be his unpaid apprentice. However, Mashiro immediately gets jealous, seeing Asunaro as competition, and challenges him to a duel. The two quickly get into a heated competition with Asunaro's own assistant, Hana "Maki-chan" Kazamaki, acting as referee to oversee the game. While the two rush off to complete a tiebreaking stamina challenge, Nagumo tells Maki that he has no intention of firing Mashiro, and that he is happy to see Asunaro be inspired by his younger self. Mashiro then manages to win the race by unleashing a surprising amount of heavy objects buried somewhere within her sailor uniform and making herself lighter.

Asunaro shows up at Nagumo's office again, but this time with a case: to find out whoever is stalking him. After Asunaro goes through clumps of his adoring female fans who undress and then redress him, Nagumo spots a man in a hoodie stalking him from farther out. After Maki manages to restrain him, the group uncovers that Nezu is the stalker, but he claims that he was actually spying on the "real" stalker, Asunaro, who was standing outside the Nagumo Detective Agency for about a month. When Asunaro confesses to watching Nagumo's office, he escapes from Maki's wrath by restraining her in the same manner that she took down Nezu.
