Not sure if people knew about this one here, but there's a Visual Novel series produced by Silver Cow Studios that is worth a look.
Time Tenshi involves time travel, and a rather unusual effect on women's bodies.
Feature temporary and (implied permanent) BE.

They've just released Time Tenshi 2 for Greenlight, and it could use a lot more yes votes !!
