Natsumajo!: Two Witch Sisters and 31 Days of Magical Resonance

The Natsumajo eroge! -Futari no Majo to Manatsu no Inaka Seikatsu- is now available sale on DLsite. It is signed by oginomesoft, a circle that is simultaneously the author, label and illustrator of the product, and which places the action in a rural village with lots of vegetation, with sea, river and forest within reach of the player.

The premise of the eroge Natsumajo is straightforward: a struggling apprentice mage is invited by two witch sisters to spend the summer training at their home. The training period runs from August 1st to 31st, and the goal is to pass the final presentation and be recognized as a fully-fledged mage.

Eroge Natsumajo: Magical Resonance as Training

The core system of the eroge Natsumajo is called magic resonance (maryoku kyōmei), and its logic is quite simple: the more physical contact there is between those wielding magical power, the stronger the magic becomes. The game’s description translates this into a detailed repertoire, including kissing, breast sucking, nipple and clitoral stimulation, three discreet penetration positions, and the use of vibrators and nipple rotors.

On screen, resonance has its own bar: filling it and ejaculating increases stats. If the energy runs out mid-session, the training is cut short and the player’s money is halved. The routine is divided between the house and the village, with mornings of practice, afternoons of fishing at sea and gathering shellfish on the beach or materials in the forest.

In the eroge game Natsumajo, the shared house operates on a schedule. The sisters go from the bathroom to the toilet and also have their alone time, which the player can interrupt. At night, the bedroom door opens: there’s a wake-up indicator, and the trick is to gently stroke them so they don’t get up; if things get too complicated, a gentle stroke on the head will lull them back to sleep.

Those who have already played the eroge Natsumajo describe it as a first work of low difficulty, with compact maps and a progression that rewards conversation: each conversation consumes energy, increases affinity with the sister in question and unlocks new scenes.

Elisa, Mina and the five neighbors

Elisa is the older sister, kind and maternal, and she teaches resonance step by step. Mina, the youngest, retains the mischievousness of childhood and uses her body to tease the protagonist. Around them are five girls from the village: Noa, a succubus who works in a nightclub; Haruka, a former guild receptionist now unemployed; Rinea, an elf in heat who runs a tool shop; Nagi, a traveling merchant who lives on the beach and has a habit of stripping; and Iris, a witch who only thinks about having fun.

The training in the eroge game Natsumajo varies depending on the sister: with Elisa it’s theoretical magic classes, while with Mina it’s running and swimming. Assessments come in three rounds, on the 10th, 20th, and 30th, and the same stats you upload at home are used later in the card minigame.

Letters, endings, and 75 scenes in memory mode

The village witches have their own vice in the eroge Natsumajo: Onee-chan★Masters, known as One★Masu. It’s a card game bought in packs at the shop, and the winner is determined by stopping a roulette wheel at the precise moment to drain the opponent’s life points. Winning against Iris is rewarded, and defeating Rinea or Iris at the table is one of the conditions for unlocking the midnight zone and making a wish at the goddess statue in the ruins.

In the eroge Natsumajo, the chosen heroine’s ending is revealed on the night of August 31st, provided the conditions are met. A save file is then created, allowing the player to restart from August 1st while retaining affinity and stats. The “Reminiscence Mode” contains 75 scenes and can be fully unlocked, a shortcut documented in the game’s ReadMe file.

The bulk of the Natsumajo eroge material is in pixel artAlthough Elisa and Mina also have unique illustrations. The protagonist is the only one who penetrates, and the rest of the cast are divided between touching, observation, and nighttime visits. The product description labels the item as touching, pixel art, sisters, cohabitation, daily life, sweet romance, sex while asleep, and large breasts.

Price, demo, and requirements for Natsumajo!

The price shown on the Natsumajo eroge listing is 2,024 yen. There are signs of a 20% discount, but the end dates on the product page and the game guides don’t match, so it’s best to check the price directly on the listing before making a purchase. The product is sold exclusively on this platform.

The file size is 531.45 MB, and the trial version is 376.03 MB. A demo is available, and the system requirements are listed for Windows 10 and Windows 11. The language list includes Japanese, English, Simplified and Traditional Chinese, Korean, and Russian, although the product information isn’t entirely consistent in this regard. As for the format, it’s classified as a voice and music simulation, in the application category, and is marked for ages 18 and up.

A useful detail for anyone installing it these days: in version 1.0 there is no exit button and you have to close it with Alt+Enter or from windowed mode.

The reasonable question is whether 31 days offer enough material for more than a string of scenes. With its time-based structure, resonance bar, three evaluations, and a finale for each heroine, Natsumajo! presents itself as a modest but well-organized debut. Which of the two sisters would you start with on August 1st?
