An employee of the Yoshida household who handles whatever needs doing—driving, security, that sort of thing. Officially he's supposed to be keeping an eye on Haru, though nobody's really fooling anyone about that being his main job.
He's the type who doesn't take things too seriously and will casually skip work when he feels like it. Not exactly the most dedicated guy.
When he's not working (or pretending to work), Andou's into eroge games and has a habit of flirting with high school girls, which. yeah, probably speaks for itself.
