From Becoming the Master of Monsters

The trumpet duo has opened a new book, and originally wanted to keep it secret for the time being, but the newbie's performance is too dismal, and if this continues, he may not be able to even test the book.

I can only shamelessly beg you to go and watch it. If you like it, add it to your favorites and vote. The most important thing is to catch up on the latest chapter. I would be very grateful.

The title of the book is "Infinite Split from Konoha", and there is a high probability that it is also a manga (╯﹏╰)
