She's a teacher who advises the Game Creation Club, though "advise" might be generous. She's notorious among club members for basically sleeping through her responsibilities—you'll find her passed out in the club room more often than actually helping out. She doesn't put much effort into keeping things running or pushing the club toward any real wins.
For reasons that go beyond just carrying a stun gun around, she refers to herself as a "lightning type." It's one of those quirks that club members have learned to accept, right alongside her legendary narcolepsy.
