Nikko quickly rushes through the hall as he runs towards his club meeting as he is late due to falling asleep during last period of school. "Why did I have to fall asleep", he thinks to himself as he runs pass by other students to get to his club room. He successfully makes it to the club room. "Ah sorry I'm late", Nikko says to them. "Took you awhile", Midori says to him as he sits down on his chair. "So what were you guys planning", he asks them. "Oh we're planning too make a special offer for tomorrow when we open up the café in the afternoon", Kichi says to him. "Ah got it", he says to him. "What should we do thought for tomorrow is the question", Emiko says to them. "What about my family special cheesecake recipe?", Nikko says to them. "You mean that insanely delicious cheesecake recipe?!", Midori asks him as her mouth is watering from hearing it. "Y-yes", he says to her while he goes back a bit due to Midori being up in his face. "Oh sorry for being too close", Midori apologizes to him. He brushes it off and says it's alright. "Man, I wish I could join you guys but I have to attend a family reunion tomorrow.", Aki says to them. "Aww, that's fine Aki. I'll make sure to save some cheesecake for you when you come to school the next day", Nikko says to her. "You will?!", she asks him with her eyes being sparked in joy. "Yeah", he says to her. They all continued to talk about tomorrow's special offer and just relaxing within the club room.
Tomorrow comes and they are all excited to open up the café to offer the students and teachers of their school with some delicious freshly baked cheesecake. While everyone is waiting for the time to open up the café, Emiko and Midori have been putting promotions through out the school about their special offer which excites the students and even some of the teachers who have been to their café before. The group hears people gossiping about the cheesecake promotion that will be going on in just a bit which gives Nikko some fright that he might fail this but Midori comforts him and tells him that this will turn out well. Lunch arrives and the group quickly rushes to their club room to open up their café. Emiko quickly sets up shop as everyone changes uniform with Nikko setting up the ingredients and appliances that he will use to make more cheesecake and Midori putting out the 5 boxes of cheesecake that Nikko has already made, and now they are ready to sell.
Everyone is enjoying their cheesecake with even Midori who is currently resting enjoying her slice whilst Nikko with the help of Emiko makes more batches of cheesecake for them to sell. "I haven't tasted this in so long", Midori says as she indulges in her slice of cheesecake. "At least you like it", Nikko says to himself as he smiles. "Huh, you seem to be smiling Nikko", Emiko says to him. "W-what? What are you on about", he stutters to say to her as he looks away from her. Emiko giggles to herself as she continues to bake her batch of cheesecake. Kichi walks into the room and asks, "How's the new batch coming up?". "They are doing quite well but what about your mentality with dealing the amount of customers by yourself", Nikko says and ask back to him. "Ah, the usual you know", he says back before washing the dishes that were left by the customers.
As Kichi washes the dishes with Emiko and Nikko who are baking some cheesecakes, Midori barges into the kitchen with a distressed look on her face. "What's wrong Midori?", Emiko asks her with also a worried look on her face. "The customers. All of them got pick pocketed and even their valuable possessions were stolen", she says to them. Everyone is shock that someone successfully pick pocketed every customer that was in the store. They look outside to see everyone is in distress and are scared to lose their belongings. "It seems it's my time to shine", Nikko says to his friend. "What?", Kichi asks him. In a blink of an eye Nikko changes out of his café uniform into his detective uniform. "Detective Nikko is on the case!", he says to them in the most flamboyant way possible. "Since when did you have that and what kind of sorcery did you just use to change into it within a blink of an eye?!", Kichi asks him with multiple questions. Nikko answers, "One, I've always owned this and do some crime solving when I'm bored. I've always been a fan of Sherlock Holmes. Second, I don't know how I did that". "Wait you don't know how you changed into that within a few seconds?", Midori asks him. "Nope! Not at all", he says to her as he laughs in a flamboyant way.
Nikko walks into the main quarters of the café and he starts asking the customers on who it might have been that did the pick pocketing. He writes down on his notepad that he miraculously pulls out of nowhere which confuses his friends even more. Nikko walks back to the kitchen and provides some newfound info. "Alright, we currently have two suspects. One of them is a clear description of a student from class 1-D which a customer said their name was "Fujita". The other suspect was describe to be quite tall and one of them known them as the student from 3-B named "Katashi". That's our two suspects for now", he says to them. "Wait Katashi? You mean the one who pushed me down to my near death back in Kyoto?", Emiko asks him. He nervously said yes to her and see her mood change to a whole new persona that scares everyone including the customers who doesn't even see her. "Aight Nikko. I'm going to tag along with you on this case", she says to him which confuses him for a moment before she miraculously changes into her own detective outfit which shocked everyone. "Where the hell did you get that from and what's your reasoning?!", Midori asks her. "Oh- same reason as Nikko really", she says to her while giggling a bit.
The two detectives leave the café and goes on a search case to find their thief and capture them. They leave the very confused Kichi and Midori behind to deal with the café and the two frantically continue to make the cheesecakes for the customers and telling them to calm down. Nikko and Emiko walk along the school hall as they search for their suspects. As they walk around they found Fujita who was about to enter his class. "Stop right there young man!", Nikko shouts at him which alerted Fujita who looks at him with confusion but slowly his face is filled with dread as Nikko rushes towards him giving him a tackle to the body which shocked Emiko. "Nikko! What was that for?!", she asks him. "Oh- I did that so he couldn't escape", he says to her. "Escape from what?", he asks Nikko in confusion. "Tell me. Did you pick pocketed the people back at our café?", Nikko asks him. "What no! I was there eating cheesecake also your baking is delicious-", he says to Nikko. "Oh why thank you" Nikko replies. "Your welcome. Anyway, I didn't pick pocket anyone even if I have the look of a thief.", he finishes his sentence before Nikko lets him go. "Well in that case. By any chance you saw a student who is tall and is called 'Katashi'?", Emiko asks him. "Oh that person. Yeah I definitely saw him doing something suspicious", he says to them. "Thank you for your info and sorry for tackling you but the two of us must go now", Nikko says to him while also apologizing to him for the tackle as the two run away to search for Katashi. "Bye bye", he says to them as he waves them away.
The two rushes towards Class 3-B and searches for Katashi. "Hey. So do you guys know where Katashi's desk is?", Emiko asks the girl of the class and they point her at his desk. "Thanks for the help" she says to them before her and Nikko walk to his desk and they are met with a note. The note reads, "I am not in class but I am somewhere where the skies are clear as day". Nikko quickly figures out that Katashi is not only the thief but is on the rooftops. The both rush towards the rooftops passing by everyone leaving them in confusion on what in the world the two are doing cosplaying as detectives. The both of them arrive at the rooftop with short breathed. "There!", Emiko says to Nikko as she points at a note that is all the way on the other side. They walk quickly to it and Emiko reads out the note that has been taped to the wall. "I hope you had fun in this chase but I'm already back at the café to steal a bit more than just valuable objects". Emiko and Nikko are quite distress knowing they don't have much time to get back to the café to stop his wrong doings. Nikko quickly calls up Kichi to notify him about what's going on.
Kichi picks up his phone to answer his call. "Yes?", he says to Nikko through the phone. "It's Katashi! He's going to rob the café again!", he says to him. "Oh Katashi? Midori already tied him up", he says back to him which leaves Nikko and Emiko in a statue like state. "Uhm... Hello?", he says to Nikko as he tries to look for a response. After a few moments later, the two walk back to the café and to their surprise it was Katashi. Emiko walks up to him and picks him up by the shirt, and just with her look of disgust made him scared. "Now give up the items and go to the principal office", she says to him in a meaner tone which even scared the others. "I admit for my sins! Please have mercy on my life", he pleads to Emiko. She lets him go and a teacher comes in to take him to the principal's office. Everyone clapped their hands and cheered the group of friends for doing a great job at solving the case. Afterwards, Nikko comes back to the kitchen and creates the biggest cheesecake that anyone has ever seen in their life which made everyone's mouth watered. "This one is on the house", he says to everyone before putting it down on the giant table that they have. Everyone enjoyed the delicious giant cheesecake together leaving them all stuffed up with cheesecake.
After a short break, everyone goes back to their classes to continue the rest of the day. In the last period, Sensei Kaito walks into class and informs the student of an important matter. "It's been a long day for all of you and I know you are all tired but I would like to inform everyone that next week we will be having our Midterm Test for the first semester. I will be providing the schedule in just a moment but I hope everyone will be ready for the upcoming exam.", he says to his students which puts everyone back into reality and it shocked them that their first exam has already arrived.
