Welcome to Tsunami Channel
A computer fairy who appears like a young woman with dark hair. A creature with powers of teleportation, transformation, creation and destruction, a being of magic and technology both, with access to the well-known (and aptly named) "hammerspace" ... Her appearance changes slightly with every system upgrade made by Professor Hasegawa. Tsunami is the Professor's constant companion, colleague and conscience -- a task she fulfills by smacking him with a hammer for acts of stupidity and/or hentai-ness. She seems to have feelings for him as well, which she is unwilling to act on. (by Aebliss)
