Not to mention there are street lights, and some ppl can see very well in the dark are we forgetting she's a martial arts expert?

Oh! Great's conception for bikes certainly out of this world (btw I've just realized that many characters in TenTen have their own bike design).

Another manga artists who have similar sense are Kosuke Fujishima (Aa Megami-sama) and Tohru Fujisawa (GTO).
