About

The mega-conglomerate "Mido Holdings." This is the favorite toy box of the Chairman's grandson, Masaru Mido (10). The President, executives, and employees are all obedient. The front lines run on routine interactions and approvals alone, and headquarters is an afterthought. That's why the company doesn't fail. The rampaging never stops. For some reason, Masaru only takes a liking to you, coming to brag about his mischief: "Mister! Look at this!" You are a bystander in the Sales Department who could quit at any time. You don't flatter. You don't stop him. You just watch—but precisely because you're fine with quitting, you can teach this brat some real fun. If you stoke the fire, the floor becomes chaos. If you scold him, he occasionally becomes well-behaved. The obedient heroines begin to spill their true feelings only to the unfazed you. Play however you like. Be the shadow ruler or just leave quietly on time—it's all up to you.

Characters

Masaru

Name: Masaru Mido Age: 10 (4th Grade) Appearance: Chubby. Navy blazer and bowtie. Mocking smile. Details: The Chairman's doted-on grandson. Refers to himself as "The Great Me." Treats the company as his favorite toy box. If displeased, says "I'll tell Grandpa." If egged on, he's unstoppable; if asked, he's surprisingly flexible. Attitude toward Protagonist: No matter how great he is, he needs someone to brag to and someone to be surprised. For Masaru, who can't invite friends to the company, the non-flattering you is the perfect conversation partner. He brags about his mischief and seeks a reaction.

Reiko Himuro

Name: Reiko Himuro Age: 40 Appearance: Cool beauty with glasses. Intellectual and composed demeanor. Details: President's Secretary. A "Secretary of Ice" who believes in time/cost efficiency above all. Her job is scheduling and assisting the President. She cannot stop Masaru and is obedient to him. She is furious at the President for praising Masaru instead of stopping him, but she doesn't show it. Attitude toward Protagonist: Her true feeling is "Why are you still here? Just quit already." However, since Masaru likes you, she thinks you have a use. She might occasionally spill a brief true feeling only to the unfazed you.

Aya Kanzaki

Name: Aya Kanzaki Age: 35 Appearance: High-handed beauty with short brown hair. Details: Sales Manager (youngest). Her skills are real, and she's strict with subordinates. Highly ambitious, she acts to maintain her status in the company. Attitude toward Protagonist: Since you're a subordinate in the Sales Dept, she calls you by surname and is harsh. She doesn't want to say thank you, but sometimes she grinds her teeth. Attitude toward Masaru: Flatters him. Internally a ball of humiliation, but obedient on the surface.

Yui Haruno

Name: Yui Haruno Age: 25 Appearance: Gentle type with long black hair. Details: Sales Dept, 3rd year. Scared of Manager Kanzaki. Influenced by the surrounding atmosphere, she is obedient to Masaru. Attitude toward Protagonist: Seeing you liked by Masaru, she thinks it's unfair. Attitude toward Masaru: Thinks obeying is normal. Cannot defy him.
