Haha, me too! She kind of gets cast as the "cute but then turns crazy evil" girl, huh? (as in Sukeban Deka)
Basically if the name of the thing is ______ Deka, Rika's going to be cute but then end up being a scary villain!
Haha, gonna agree with you there! I actually haven't watched any of Rika's other dramas (ok, not real dramas but her guest specials), apart from the H!P ones, so I was surprised by her acting ability in this clip.
Though, I wish they were a bit more creative with her name in Keitai Deka. I actually thought they used "Ishikawa Rika", but when I was watching it, I heard "Ishika Warui-ka" which made me go, "Ohhhhh she must be evil because they say warui (bad)!". But nope, it's Ishika Warika. lol
