Laino (or as you Earthlings would say, Lain) is, without a doubt, the most mistreated character I've ever had the pleasure of creating. Counting the incest twins who were brutally mutilated by their father.

What can you say about Lain, except that she is the janitor of the foos? Not to imply that being in the cleaning system would signify you as lowly or in a frowned upon career. It's just that in Lain's case, she is horrible at her profession. When alone, she will piss and moan like an infant about her situation, then continue to do a half-assed job. And really, who can blame her. Shley will always make a beeline for her when in the general area to command her to work harder, think less, shut her piehole, and so on. This just encourages her to slack off more, creating an endless cycle of opression and hate.

Deep down, we all have an urge to kill our superiors. Lain just likes to express it in a physical way, i.e. with frying pans, knives, axes, samurai swords, and so on. She manages to get a few punches in when Shley's feeling especially low, but deep down, all Laino wants to do is love and be loved by someone or something. But most likely, it'll end up being something.
