This historical action manga follows a Japanese warrior's journey to Europe in search of vengeance, at the height of the Thirty Years' War. Vinland Saga meets Shogun in this American Manga Awards-nominated masterwork. The year is A.D. 1620. Europe is riven with the conflagrations that will grow into the Thirty Years War. Catholic and Protestant forces clash across battlefields ruled by sword and gunpowder alike, and mercenaries of every stripe ply their trade. Among them is Issak, a lone Japanese warrior wielding a matchlock gun of strange design, on a sworn mission to find and kill the man who murdered his master and fled Japan for the other side of the world. Extra-long omnibus edition contains Vol. 1-2 of the Japanese release.","forthcoming":false,"isbn13":"9798888774953","publication_date":"20250610","publisher":"Kodansha Comics","slug":"issak-omnibus-1-vol-1-2","subtitle":"","title":"Issak Omnibus 1"},"discovery":{"categories":{"all":[{"bisac_code":"CGN010020","confidence_band":"high","label":"Medieval Historical Comics","score":0.8717,"source":"bisac_hint_model"},{"bisac_code":"CGN004050","confidence_band":"medium","label":"General Manga","score":0.7927,"source":"bisac_hint_model"},{"bisac_code":"CGN004060","confidence_band":"medium","label":"Tie-In Comics","score":0.783,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"CGN010020","confidence_band":"high","label":"Medieval Historical Comics","score":0.8717,"source":"bisac_hint_model"},{"bisac_code":"CGN004050","confidence_band":"medium","label":"General Manga","score":0.7927,"source":"bisac_hint_model"},{"bisac_code":"CGN004060","confidence_band":"medium","label":"Tie-In Comics","score":0.783,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"CGN004050","confidence_band":"high","label":"General Manga","score":1,"source":"onix_publisher_code"},{"bisac_code":"CGN010020","confidence_band":"high","label":"Medieval Historical Comics","score":1,"source":"onix_publisher_code"},{"bisac_code":"CGN018000","confidence_band":"high","label":"COMICS & GRAPHIC NOVELS / Action & Adventure","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Medieval Historical Comics","score":0.8717,"slug":"medieval-historical-comics"},{"label":"General Manga","score":0.7927,"slug":"general-manga"},{"label":"Tie-In Comics","score":0.783,"slug":"tie-in-comics"}],"reader_fit":["For readers interested in historical action manga and the Thirty Years' War."],"related_lists":[],"series":null,"similar_books":[{"authors":["Shinji Makari"],"book_id":"9798888774977","cover_image_url":"https://img.bookfrontier.com/9798888774977.jpg?v=1fec1f77798c65f3","score":0.9555,"title":"Issak Omnibus 3","url":"https://bookfrontier.com/books/9798888774977"},{"authors":["Shinji Makari"],"book_id":"9798888774984","cover_image_url":"https://img.bookfrontier.com/9798888774984.jpg?v=6144be3bb3382ee6","score":0.9497,"title":"Issak Omnibus 4","url":"https://bookfrontier.com/books/9798888774984"},{"authors":["Shinji Makari"],"book_id":"9798888774960","cover_image_url":"https://img.bookfrontier.com/9798888774960.jpg?v=28b4f1bdd7f0790b","score":0.9485,"title":"Issak Omnibus 2","url":"https://bookfrontier.com/books/9798888774960"},{"authors":["Makoto Yukimura"],"book_id":"9781612624211","cover_image_url":"https://img.bookfrontier.com/9781612624211.jpg?v=fc78f71a61369bfe","score":0.8208,"title":"Vinland Saga 2","url":"https://bookfrontier.com/books/9781612624211"},{"authors":["Makoto Yukimura"],"book_id":"9781612624204","cover_image_url":"https://img.bookfrontier.com/9781612624204.jpg?v=d6685b84b3cc4c45","score":0.8156,"title":"Vinland Saga 1","url":"https://bookfrontier.com/books/9781612624204"},{"authors":["Makoto Yukimura"],"book_id":"9781646519552","cover_image_url":"https://img.bookfrontier.com/9781646519552.jpg?v=fb5adca775bf29f3","score":0.8038,"title":"Vinland Saga 14","url":"https://bookfrontier.com/books/9781646519552"},{"authors":["Makoto Yukimura"],"book_id":"9781646510771","cover_image_url":"https://img.bookfrontier.com/9781646510771.jpg?v=01599f14754431ee","score":0.8015,"title":"Vinland Saga 12","url":"https://bookfrontier.com/books/9781646510771"},{"authors":["Makoto Yukimura"],"book_id":"9781632368034","cover_image_url":"https://img.bookfrontier.com/9781632368034.jpg?v=a9a34300faeae0ee","score":0.8006,"title":"Vinland Saga 11","url":"https://bookfrontier.com/books/9781632368034"}],"topics":[{"evidence_refs":["keyword:historical graphic novels"],"label":"Novels","score":0.152,"slug":"novels"},{"evidence_refs":["keyword:manga volume 1"],"label":"Manga","score":0.1437,"slug":"manga"},{"evidence_refs":["keyword:historical graphic novels"],"label":"Graphic","score":0.1371,"slug":"graphic"},{"evidence_refs":["keyword:medieval historical fiction"],"label":"Historical","score":0.1137,"slug":"historical"}],"what_you_get":["Themes: Vengeance, Religious conflict, War.","Pacing: fast, momentum-driven storytelling.","Story elements: Lone warrior on a revenge mission."]},"llm_signals":{"confidence":0.84,"pacing":"fast","reader_fit":["For readers interested in historical action manga and the Thirty Years' War."],"themes":["Vengeance","Religious conflict","War"],"tropes":["Lone warrior on a revenge mission"]},"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":true,"similarity_seed":true},"stats":{"amazon_ratings_count":12,"goodreads_ratings_count":81,"goodreads_reviews_count":40,"quality_score":0.886}}
