It is very useful as a English viewer to see the questions and comments being responded in subtitles. I would like to request a video how did shinobi's fought with weapons like grappling hook, sickle (kama), and using taijutsu. Historically it was impossible for ninja's to poses katana unless if one of your teammates were to be samurai. They were thought to be the landscapers of the time, also known as "oniwaban" in Japanese terminology. So they were mostly thought to fought using gardening tools, pharmaceutical tools, and through intelligence. For more samurai and ninja related contents and resources, I actually look into this author from UK and his name is Antony Cummins who published books like "The Book of Ninja" and "Iga and Koka Ninja Skills".
