# Science Adventure Watch Order Also known as: Science Adventure series, Chaos;Head, Chaos;Child, Robotics;Notes, ChäoS;HEAd, ChäoS;Child Source: https://www.animechrono.com/franchise/science-adventure Last updated: 2026-10-31 Last checked against current sources: 2026-10-30 AnimeChrono watch orders put every season, movie, OVA, ONA and special in chronological story order, mark optional entries, say where to start, and are maintained by signed-in fans with versioned edits that can be reverted (4 entries in this order). The Science Adventure watch order covers the anime adapted from 5pb. and Nitroplus's visual novel series, which share one world and a few characters. Steins;Gate, Steins;Gate 0 and the film Load Region of Déjà Vu have their own Steins;Gate watch order page, so they are not repeated here. In in-world order, start with Chaos;Head (Episodes 1-12, 2008), set in Shibuya in 2009. Steins;Gate (2010) comes next. Chaos;Child (Episodes 1-13, 2017) is Chaos;Head's direct sequel, set six years later; the film Chaos;Child: Silent Sky (2017) adapts its true ending and should follow straight after. Robotics;Notes (Episodes 1-22, 2012-2013) takes place in 2019 and refers back to Steins;Gate, so watch it after that. Each story mostly stands alone. Occultic;Nine is a separate series by the same creator, not part of Science Adventure. ## Recommended first watch Most viewers start with Steins;Gate (own page). For the rest: Chaos;Head (12 episodes), then its sequel Chaos;Child (13) and the Silent Sky film, and Robotics;Notes (22), best after Steins;Gate. Each story mostly stands alone. ## Start here Start with Episodes 1-12 (Chaos;Head). Nothing in this order is marked optional. ## The chronological order 1. Chaos;Head: Episodes 1-12 2.
