Eichi Tankyuu Seishitsu- -v1.0- -rj01200699- May 2026

This is the initial release version.

To put RJ01200699 in context against similar catalog numbers:

This is not a "fall asleep in 10 minutes" work. This is a "lay down in a dark room at 2 AM and question your existence" work.

To understand the product, one must first understand the poetry of its name. The Japanese phrase breaks down into three distinct concepts:

Put together, "Eichi Tankyuu Seishitsu" translates roughly to "The Nature of the Quest for Wisdom." Playing the title backward—Seishitsu, Tankyuu, Eichi—suggests a structural loop: Through understanding nature (Seishitsu), one embarks on a quest (Tankyuu), arriving at wisdom (Eichi).

This is not a casual title. It implies a narrative-driven, possibly philosophical, audio experience. Eichi Tankyuu Seishitsu- -V1.0- -RJ01200699-

Since this is a narrative-driven game, progress relies on "Flags" (hidden triggers).

General Tips for V1.0:

Eichi Tankyuu Seishitsu! (Ｈ？英知？探求性質！), identified by the DLsite product code RJ01200699, is a Japanese adult exploration and simulation game developed by the circle Guchi Wotabatake (愚痴ヲタ畑). Released as version 1.0, the title translates roughly to "H? Wisdom? Investigative Nature!" and centers on the scientific inquiry into human sexuality through the eyes of a brilliant but socially naive protagonist. Storyline and Premise

The narrative follows Shino, a "muchimuchi" (plump and curvy) beauty and genius researcher who has almost no interest in anything outside of her scientific studies. The story kicks off when a minor event causes her to realize that others view her body in a sexual light. Intrigued by this physiological and psychological phenomenon, she decides to apply her rigorous scientific methods to research her own body and sexual responses.

As she explores various locations, Shino begins to "investigate" why her large breasts and body attract so much attention, often displaying a complete lack of initial shame as she exposes herself in the name of data collection. Gameplay Mechanics

The title is structured as an exploration-based simulation where players navigate various environments to progress through Shino's research journey: This is the initial release version

Data and Keyword Collection: Progression relies on visiting different locations to gather "keywords." These are obtained through interactions with the environment and other characters.

Invention System: A central mechanic involves an invention screen where gathered keywords are combined. This allows Shino to develop new items or "research products" that are necessary to unlock further story beats and different narrative paths.

Environmental Interaction: The map includes various public and private settings, such as educational facilities and recreation areas, which serve as the backdrop for Shino’s unconventional field studies. Key Features and Content
