■ Introduction to "Junior High English Vocabulary Even Sakura Miko Can Understand"
"Junior High English Vocabulary Even Sakura Miko Can Understand" includes approximately 1,000 words that junior high school students should know. Matching Sakura Miko's level, who struggles so much with English that she stumbles even on how to read English words, this reference book is unusual for junior high school students, as all English words and example sentences have Katakana furigana. Also, English example sentences can be learned through familiar phrases related to game streaming and distribution activities, which are close to fans. Furthermore, in the opening pages, you can learn related English words with full-color scene illustrations related to Sakura Miko, such as the cyber shrine, live stage, and streaming room. It also includes English words related to streaming and "oshi-katsu" (supporting one's idol), making it a valuable book for interacting with overseas fans.
Comes with an original notebook "Miko Learning Notebook English".

■ Introduction to "Junior High Mathematics Even Sakura Miko Can Understand"
Matching Sakura Miko's level, who is terrible at mathematics, this book reviews elementary school arithmetic levels. Elementary school learning content, such as fractions and percentage calculations, contains surprisingly important information, and if this is ambiguous, junior high school students will struggle with mathematics. This book, which allows for effortless review from elementary school, will be a helpful resource for junior high school students who are worried about "not being able to ask the teacher anymore."
With fun interactions between Sakura Miko and 35P (Miko P), students can gently learn through quiz-style questions.
Comes with an original notebook "Miko Learning Notebook Mathematics".

■ Introduction to "Junior High Kanji + Vocabulary Even Sakura Miko Can Understand"
All 700+ example sentences for Kanji and four-character idioms are related to Sakura Miko, making it a reference book that fans can also enjoy as a reading material.
In the Kanji section, students will learn how to read and write Kanji by themes such as VTuber activities, idol activities, Sakura Miko's daily life, listeners' daily lives, game streaming, and study streams. The Kanji learned are carefully selected from those frequently appearing in entrance exams, representing content that junior high school students should actually remember.
Furthermore, Sakura Miko has made her fans laugh with various misreadings, such as misreading "阿鼻叫喚" (abi kyoukan - pandemonium) as "あえんびえん" (aen bien - a misreading). This book is rich in vocabulary sections, including four-character idioms and proverbs useful not only for junior high school students but also for adult conversations. Students can enjoy learning how to use vocabulary through conversations between Sakura Miko and 35P (Miko P).
