I enjoyed it but I just don't get how the brother became Fuma and became the 20th. He's from different bloodline. How does the power transfer? Also why the enemy was the one who jumped to get Gaku. Why the family just watch him drown? Do Shinobi don't know how to swim? (Haha jk). I love the grandma and the kid scenes! So fun to watch! I hope season 2 will be better.
