Ad Aquilonem: Seto's 100 Days launches on Switch on 30 October, with training choices, ruin expeditions and 14 possible endings.
MBA International has announced that Ad Aquilonem: Seto’s 100 Days (Ad Aquilonem - セトとすごす100日間 -) will launch on Nintendo Switch on 30 October. The training simulation follows Seto, an anthropomorphic boy, through a hundred days of training, rest, exploration and companionship. 12
The game will cost ¥2,200 in Japan, with a launch price of ¥1,980 until 25 November. The official campaign site says the Switch version is launching first, while the Steam release does not yet have a date. 1
Training Seto for the ruins
Each day gives players choices about how to spend time with Seto. Training can raise stamina, strength, intelligence or speed, while resting helps prepare him for the next challenge. The player’s routine also affects Seto’s personality, which can develop towards a wild or cool temperament. 12
Exploration uses the abilities built during those hundred days in automatic battles across ruins. Players also choose skills for each expedition, adding a light strategy layer to the game’s life-sim structure. Between trips, the official site shows players furnishing a room and spending time with Seto by talking, petting him or playing rock-paper-scissors. 1
The game has 14 possible endings based on how players raise Seto and how they spend their days. MBA International is also discounting the previous action game, Ad Aquilonem: Seto and the Ruins of the Wind, to ¥1,788 from 30 October to 25 November. 2
Our opinion
The appeal here is the clear loop rather than a vague promise of cosy living: train Seto, make time for him, then see whether those choices hold up when the ruins push his abilities. The split between a wild and cool personality gives the routine a visible consequence, while 14 endings should make the hundred-day structure feel more deliberate than a simple calendar countdown. The Japan-only, Japanese-language launch limits its immediate reach, but the official material gives this small simulation a stronger identity than its gentle presentation first suggests.
