The mouse, scheduled for a March 2009 release and priced at ¥6300, is apparently meant to actually be used, as it carries with it a serious spec sheet:
Size:62x112x32mm (W x L x H)
Optical Sensitivity: 800cpi
Compatible with Windows 98SE/2000/Me/XP/Vista/Mac OS X 10.2+
For fans more into tsundere, a Tomoyo Sakagami version will also go on sale at the same time.
Unfortunately, the pre-order window for these attractive ita-mice was quite short, and pre-orders seem to be closed at all the online stores that are carrying them.
Perhaps fans will be able to pair the mice with a suitable computer, along the lines of a Strike Witches Ita-PC?
