...I think that Hajime's story arc is my favorite out of all the Kamen Riders I've watched up until now. *_*
I mean, the Hoppers' arc(s) are really interesting and intriguing and I LOVE their combined story a lot in all of its dysfunctional, fucked up glory (and it inspires Epic Fics!!!one1! which means fangirling-wise, the Hoppers are at the top of my fandom love scale)... but Hajime's is... well, because it's a story of overcoming the dark side in yourself against REALLY great odds and coming out stronger and wiser and happier (his SMILE after he henshins back into Hajime in the river, and as he washes his face *_*) for it, it's just really awesome. For similar reasons as to why Shishido's is my favorite in PoT, actually, except much more so.

Actually, Morimoto Ryoji fits my idea of Shishido really well, physically.
