【Yui Oguro】A book about masters who fight against their guesses [Preparatory Issue].

A strategy book with contributions from FG●’s badass masters.
This time, a master with over 18,000 boxes of gacha has joined the fray!
This is the first time I’ve been able to get a copy of the book.
High difficulty TA and collection of materials for mounted mackerel.
(Due to the cancellation of Comiket, the whole thing will be re-recorded at the end of the year, etc.)
