I just finished watching the first season, and I was having a hard time following some parts. The references to the past events and factions throws me quite often. I will most likely rewatch everything again.
I definitely loved the cast so much including the side-characters that barely gets any scenes. Gotta say Kimi, Toori, and Futayo are my favorites at the moment. The actions scenes were very fluid and jaw dropping especially episode 5. The humor was superb too. Always makes chuckle and its all thanks to the eccentric Toori. lol
Ah, I can't wait for the second season to come.
