Why no one likes Hibiki's second half? First part just boring. I see something is happening, but I can't help thinking that we are looking some cheap drama, without anything Rider-related.
While second part introduce us Yuichi Nakamura(He is the man, who will become Yuuto Sakurai/Zeronos. I think I do not need to say anything more) as Kyousuke Kiriya, who is finally bring us some conflict and ambiguity in season. I do really enjoyed watching his rivalry with Asumu(and Asumu being forced to be in this rivalry). It has some great plots like Shuki's and Zanki's episodes. And above all - Asumu didn't become Oni. He chose the thing he really wanted to do. Same with Kiriya.
Because of second part, I now remember Hibiki as great series worthy being Kamen Rider.
The only problem - they really should had started with "new" team from the beginning. Sudden change of season's focus in the middle of series always brings negative expression.
P.S. IMO, Hibiki's Movie, which was done with new team, is one of the best KR Moves ever.
P.S.2. New team has started working since 22 episode, but together with old team. And since 31 episode old team was completely removed.
