Some people like Wataru like him but others think he is just "too" shy. The series started off as Wataru being the "This world is posionous" but right up to when he met Mio-san he became a more social person. It was kind of strange that Wataru would suddenly go out with Mio when he hated the world...Enough of the social "stuff"'

Anyway..who likes Wataru? Whats my answer?
Well at times Wataru is really awsome, but sometimes i really didn't get him when in one certain episode(forgot which) he didn't want to morph because Mio-san was there but in episode 30 Wataru just de-henshin in front of Nago! I mean Wataru should have been smart enough to know that Nago was there...

Wataru was facing the back , he was kinda in a puzzled when Rook ran away too , so he did not turn back before noticing Nago was at the back .

It was bound to happen sometime.

I actually rather like Wataru because you can see his personality changing over the course of the series. He started almost germaphobic, then went to extremely shy and wanting to be more social, and slowly opened up since then. He especially gained a bit of confidence when Mio came into the picture.

It wasn't really all that sudden for Wataru to actually want to go out with Mio... he really started to open up slowly at the beginning... He was "attacked" by Megumi about it and he even made his first friend. He was inspired by Nago and such... I don't think he could really be compared to his self at the beginning of the show after 20 episodes later. You could complain about him being quick to change if this all happened in the span of less than like 10 episodes, but I feel that it's been long enough in his character development for all this to happen. I guess that's why I like his character and how he develops as a person in this show. I guess the big boost in social conduct with others was after he met Mio-san, who was someone that was similar to him in personality and such... Gotta thank Kengo for inviting (forcing) him to go to that group date...

I don't think it was that weird for Wataru to de-henshin that time at episode 30, unless you had a much better idea for a plot to get Wataru's identity blown and found out by someone. Nago and Wataru were fighting against two different enemies, and the enemies escaped. Not knowing that anyone would be around or be behind him, he would de-henshin because he didn't need to stay in that form. Besides, Nago was pretty much led there chasing after Abel, until he saw Kiva alone.

Aww, yay. Wataru gets his own thread, lol. He is the protagonist of the story, so he deserves it.
What I like best about Taru is that he's constantly growing as a character and he's so utterly sweet, but also strong. It will definately be interesting to see what will occur in his story next. From what I've read in spoilers, it's bound to get good. But I won't talk about that here

I think, it's awesome to see how Wataru's character changes.
Since he got very active people arround him , he just has to change, ne?
*hmm*

as far I have been watching the show I like how Wataru has been progressing...But there are still question about him..like how did he meet Sizuka for the 1st time...when did he meet kiva or he have him when he was born...too bad thou Gengo got mad at him...

Hmm..
It's not said..
But I could think, he met Shizuka, when he did one of his Vanish collecting.
@.@
About Kivat, I'm not sure..

Is it just me or did the show never tell you how Wataru got his powers?

Taru is a haft fangire witch he got from his mother then he need kivat to unleash some of his power...and tatsulot to further unlock his power...if they will tell how wataru meet kivat III then it will tell how he got his power...

They haven't told how Wataru's powers were achieved because it's a part of his origin which they aren't going to reveal until later...

I like Wataru too.
Reasons?
Well
like you said he is TOO SHY up until he met Nago-san and Kengo
and he become more and mroe social that ever when he first Met Mio-san
(But that Tofu dude just ruin it,Thy could have Kissed each other or do something lol)

Wellif u watched Climax Deka
in the beginning Kivat told a story about 22 years ago(After Otoya died?)
and I think it was Kivat who met Wataru first(I think it was inside Castle Dron)
so yea

I'm really glad Wataru had his own thread now! What I love most about wataru is that he's been changing throughout the entire series. In fact, He's one of the most developed Kamen Riders I've seen so far. (Not, that I've seen too many Kamen Riders series so far.)
For example, when he first met Kengo and Nago, he became nore confident. When he met Mio he became willing to protect someone. In the episode where he met the the Archer (episode 18), both we as the audience and he, as a fighter, learned why he was fighting. To see a character learn something about himself like that resonates deeply with the audience. These reasons are why I love wataru, and why I am a "watarufan."

I like Wataru
especially when he's fighting or when he's angry
but I like characters like Otoya more
Wataru is too "silence" and less funny
