Trianthology

TRianThology ~Sanmenkyou no Kuni no Alice (トライアンソロジー ~三面鏡の国のアリス~) is a Japanese visual novel by 07th Expansion. The story is divided into three arcs: Vespio 2438, School Love Adventure, and Country Girl, each of which feature completely different stories and UI elements. Vespio 2438 involves a science fiction setting examining both war and aliens. School Love Adventure takes place in a galge school setting following a harem story. Country Girl follows a group of childhood friends who reunite after drifting apart in high school. All three arcs are connected. The game was released August 31, 2016.

Story
TRianThology opens with a witch named Alice lamenting her boredom to her servant, Usagi. To satiate Alice, Usagi gives her three fragments that she has yet to explore and asks her to experience them simultaneously, in a piecemeal fashion, rather than experiencing them one-after-another. Alice agrees and jumps between School Love Adventure, Country Girl, and Vespio 2438.
