Your character is a lowlife without the protection of a Crime State. While trying to find shelter from a storm, you end up sleeping in a run-down building. Little did you know, it's actually the invention lair of Tokyo, located in the western wing of a huge skyscraper in a big city. They kidnap you with a clever invention and take you to the crimelord. You meet him, Capo, and his right-hand woman, whose name is not revealed but who is introduced as "The Spider". Present are Romeo and Ross, the children of the two lords. The Spider wants to kill you as punishment for stumbling on Tokyo's work, but Romeo takes a liking to you, and Capo allows you to join the State, named Ragnatela, as a runner since their old one made the mistake of asking The Spider on a date. For your first day (which is treated as an introduction to the game), you are told to head to the weapons vault and bring an envelope from the weapons man to the communications guy on the top floor. You head to the vault, where you are greeted by Oran, who banters you and gives you the message, which is inside an envelope covered in stickers. You take it to communications, where you give it to Noah, who finds it full of black confetti that explodes everywhere when he opens it. It's some boring statistics, but you get to know Noah a little bit as well. You then end the day and the introduction with it.
From this point onwards, the player is given different errands to run, usually comprising delivering messages to one character or another, and you get to interact with the characters and talk to them, making choices and gaining and losing friendship points. You must walk around the building to find each character; you can find Tokyo in their inventing lair, Romeo in his bedroom, Noah in the communications hub, Oran guarding the vault, and Ross outside the front door. They each have schedules and are absent on certain days of the week. Over the first 5 days of the game, you get to know the characters, learn pieces of their backstory, and gain friendship points with them. Once you earn enough points with a character, they will ask you to join them on their next mission. Each mission is a different minigame, each in the style of a retro arcade game; how well you perform will dictate how many points you get out of it. After gaining a certain amount of points from the missions, you are able to ask them out on a date. You then get a cutscene (the first date is always the same no matter how you treat the character), and this character officially becomes exclusive, making your day-to-day interactions more personalised. You may ask them on a second date where, depending on your interactions and choices, you will either get a bad ending or a good ending for that character.
