The "しゃべるコミックスアプリ殺せんせーの抜き打ちテスト" app, developed by SHUEISHA Inc., is a lifestyle app available on the iPhone platform. This app is the official application for the comic series "暗殺教室" (Assassination Classroom) published by Shueisha.

Using image recognition technology, this app allows users to scan the covers of volumes 1 to 13 of the comic series. Once recognized, the user's smartphone becomes the "mouth" of the character "殺せんせー" (Koro-sensei), who then presents surprise quizzes based on the content of each volume. There is one quiz question per volume, totaling 13 questions.

For each question answered correctly, users will receive a special wallpaper as a prize. Additionally, users who answer all 13 questions correctly will have a chance to win a special prize in the form of a gold tentacle through a lottery.

Please note that this app utilizes voice recognition technology, so it is recommended to use it in an environment where the app can easily recognize voice input. The app's performance may vary depending on the smartphone device and the environment in which it is played. It is also advised to remove any obstructions, such as book jackets, when scanning the comic covers. Please note that the app does not support certain smartphones, such as those with voice input compatibility issues or certain SIM-free devices.

Recommended environment: iOS 7 or later, iPhone 4S or later.
