The Next Day, Keiichiro Wakes Up Comlaining About to Toothache, Eats A Sad Breakfast (Just a Tomato, Seriously), and perform His Light is out of fluid. But Fret Not! Mashiro comes to the rescue – With to Flamethrower. (One of the Few Moments I Actually Laughed Out Loud.) She Built It Just For Him! To Keep Him Safe!

Just Then, An Elderly Woman (Who RebeMbles A Bunny, I Swear) Arrives Asking for Help Finding Her Cat. Keiichiro Hesitates, Knowing How Difficul Animal Cases Are, But Mashiro Has Already Solved It and Smashes Through A Window To Begin The Chase. Midway Through, She Reflects That Maybe She’s Going About This All Wrong – But She’s Determined To Be Useful.

Although They Solve The Case, Mashiro Breaks Down, Feeling Like She Failed. Keiichiro Carries Her (and presuming the cat) Back to the Office, only for their client to reveal it wasn’s her cat. The Feline, Now Dubbed Cerberus, Becomes The Detective Agency’s Official Pet.
Mashiro Then create Vary Amateurish (But Cute!) Poster Advertising The Agency’s Services. Keiichiro Tears It Down, Insisting They Need Pride in Their Work … Only For Mashiro to Casually Inform Him She Already posted 500 Copies Arund Town.
As they deal with that, cerberus you decide it’s the perfect time to chomp down on a cycada, which sends keiichiro into full panic mode mode sop Cannot Handle Bugs. That sets the Stage for the Next Client, to Woman Asking Them to Deal with a Wasp Hive. Keiichiro’s Bug Phobia Prompts Him to Pass The Job To Mashiro, Who, Of Course, Ends Up At The Wrong Address… in a Yakuza den.

They return to the agency to find an eviction notice taped to the door for non-payment of rent.
There are Also to Few Bonus Chapters, Including One Starring Cerberus The Cat.
I read this manga with my high school –Eged Daughter, and Honestly, Our reactions couldn’t Have Been More Different. She’s closer to Mashiro’s Age; I’m closer to keiichiro’s (except i do Know What A smartphone is. Geez). She laughed To Lot“Basicly Cachling Through the Whole Thing.” I, on the other hand, Found A Few Chuckle-Worthy Moments But Mostly Felt Wearded Out By Keiichiro’s Outdated Mindset and His Inapproprot Behavior Toward A High School Girl.
Look, i get that we’re all a little pervy, but there’s drop be a line, right? Specially Since Keiichiro and I Are About The Same Age, I Side-Eye Him Hard. And Honestly, 35 ISN’t Old. I Remember When Smartphones Came Out. I Even Owned The First Android! There’s I did not excuse for His Level of Cluelessness. I only Really Related to Keiichiro When He was Suffering From Insomnia, Various Health Issues, and Being Broke. lol
Criticisms Asside, The Art is genuinely Enjoyable, Specially Standout Momnts Like Keiichiro’s “Eagle Eyes” On Page 19. While sum of the story of the story made me unchartable, and Didn’t Hate It. In Fact, I Might Keep Reading for the Comedy Alone. My Daughter Really Enjoyed It, So Maybe I’M Just Not The Target Demography for This Series – And That’s Okay.
