First of all good video and reaction! So an explanation and recommendation for this point in the story if you are aware in other comments they mention jump straight to season 2, but why? until' episode 15 the anime follows the canon story (the manga story) but because of the times there was very little material from the manga to finish the anime so “16”, “17”, 18, 19, 20, 21, 22, 23, 24 were original anime an another different story now why I select ("") episodes 16 and 17(first half of the episode) have some scenes that are similar to the manga however there are some changes so that the first season could be finalized -My recommendations (optional)- watch 16 and 17(first half of episode 17) and skip to season 2 of the Kyoto saga and then you can continue to season 3. but if you are interested you can watch the end of season 1 just keep in mind that from 16 to 24 is a different story than the manga. Just a word of caution to avoid confusion when starting season 2
