The three friends fail their exam, and they have to attend a supplementary class on the first day of summer. During their supplementary class, a helicopter from the Self-Defense Force suddenly lands on the school ground. The soldiers explain to their teacher that the town is in lockdown due to a nano machine attack. The three friends watching everything from their classroom are in shock when they see their teacher suddenly getting devoured by a huge number of ants.","published":{"start_date":"2022-06-10","end_date":"2023-03-10","start_date_is_estimated":false,"end_date_is_estimated":false},"status":"completed","is_licensed":false,"content_rating":"safe","type":"manga","rating":64.05,"popularity":{"global":{"current":35517,"history":{"1d":35520,"1w":35042,"1mo":35028,"3mo":26539,"6mo":25795,"1y":43749}},"type":{"current":24297,"history":{"1d":24301,"1w":24104,"1mo":24215,"3mo":19727,"6mo":19242,"1y":33782}}},"publishers":[{"name":"Kodansha","type":"Original","note":null}],"last_updated_at":"2026-09-02T21:14:26.015Z","source":{"anilist":{"id":150285,"rating":6.6,"rating_normalized":66},"anime_planet":{"id":"manatsu-no-grey-goo","rating":null,"rating_normalized":null},"anime_news_network":{"id":25755,"rating":null,"rating_normalized":null},"kitsu":{"id":64020,"rating":null,"rating_normalized":null},"manga_updates":{"id":"rrrkqj5","rating":6.21,"rating_normalized":62},"my_anime_list":{"id":147875,"rating":null,"rating_normalized":null},"shikimori":{"id":147875,"rating":null,"rating_normalized":null}},"rating_count":104,"final_volume":5,"total_chapters":40,"titles":[{"language":"es-la","traits":[],"title":"Goo Gris de Mediados de Verano","is_primary":true},{"language":"ja","traits":["native"],"title":"真夏のグレイグー","is_primary":true},{"language":"th","traits":[],"title":"Gray Goo ฤดูร้อนวิบัติ นาโนมหันตภัย (SIC)","is_primary":true},{"language":"en","traits":["official"],"title":"Manatsu no Grey Goo","is_primary":true},{"language":"ja-Latn","traits":["native"],"title":"Manatsu no Grey Goo","is_primary":true},{"language":"ru","traits":[],"title":"Серая слизь в середине лета","is_primary":true}],"cover":{"raw":"https://s4.anilist.co/file/anilistcdn/media/manga/cover/large/bx150285-qfK4X8Inc2Rt.png","x150":"https://cdn.mangabaka.dev/imgproxy/plain/x150@1/aHR0cHM6Ly9zNC5hbmlsaXN0LmNvL2ZpbGUvYW5pbGlzdGNkbi9tZWRpYS9tYW5nYS9jb3Zlci9sYXJnZS9ieDE1MDI4NS1xZks0WDhJbmMyUnQucG5n","x250":"https://cdn.mangabaka.dev/imgproxy/plain/x250@1/aHR0cHM6Ly9zNC5hbmlsaXN0LmNvL2ZpbGUvYW5pbGlzdGNkbi9tZWRpYS9tYW5nYS9jb3Zlci9sYXJnZS9ieDE1MDI4NS1xZks0WDhJbmMyUnQucG5n","x350":"https://cdn.mangabaka.dev/imgproxy/plain/x350@1/aHR0cHM6Ly9zNC5hbmlsaXN0LmNvL2ZpbGUvYW5pbGlzdGNkbi9tZWRpYS9tYW5nYS9jb3Zlci9sYXJnZS9ieDE1MDI4NS1xZks0WDhJbmMyUnQucG5n","blurhash":"|bI#=UtQElfOR*ofxZs:V[p{W=JDj@RkjYt7fkj[RWWWIsW.oeaef+W;ax9ZW.Rioft6ofofbIRjjIa~sSj@oLbHoeWBj[tRofV@oeoeWpofWBWB-:WBWAbHt7s:RjofbHRjogjYa}t7WBRkoLj[RmWWRka|kCWVa#j?ay","width":460,"height":658},"anime":{"exists":false,"start":null,"end":null}}}
