Everything I Loved Became "Oneshota"! “Spy Maid Boy,” a Primé SLG Training a 180cm+ 20-Year-Old Male Maid With Strong Onee-sans

Apparently, the Mecha-Kure characters' eyes are never visible at any point during the game, and there are no plot twists either.

Wakuwaku Games has launched the Steam store page for "Spy Maid Boy," a male maid-training simulation game developed by Arenism.

A Double Life: Maid by Day, Spy by Night

In this simulation and romance game, the protagonist “Kairi” (a 20-year-old male rookie spy) infiltrates a mansion as a temporary maid for two years to uncover the secrets of a certain jeweler. In the morning, he diligently performs his duties as a maid to boost his stats; during the day, he interacts with others; and at night, he secretly gathers intelligence on his target while carrying out his spy missions.

The cast of unique older-sister-type characters are all strong, powerful women over 180 cm tall—and they don’t lose their edge even when they show their softer side. You can choose from a variety of playstyles: interact with these tall, strong women, extract information while being doted on, enjoy heart-pounding romance, or even end the relationship as just friends.

Developer Allen commented in the “Wakuwaku Games Newsletter, October 2026 Issue,” which was streamed on YouTube: “I intended to make a galge, so I created a male protagonist, but when I tried to include everything I liked, he ended up becoming a male maid.”The fact that all the heroines are over 180 cm tall is also “because that’s what I like,” and he noted, “All the heroines ended up being really tall. It turned into an ‘onee-shota’ game.”

The game features “Heart Mode,” which offers heart-pounding moments, and “Clover Mode,” where you can become friends with everyone. It can be played both as a gal game and as a standard simulation game.


“Spy Maid Boy,” the new title from the developer of “Murayaki Villain,” is scheduled for release on PC (Steam).
