Time Tenshi

Time Tenshi is an anime visual novel about secret time-travel experiments at a hidden research facility. You follow Rose and Kyo, the Time Tenshi, as they travel into the past under the supervision of Tensai Shiro, who invented the Time Window, and Michelle, the facility’s Commander and Operations Manager.

The Time Window

Time travel remains dangerous and experimental, and the Time Window has not been tested on male subjects. Only women can safely travel through it, and they undergo surprising bodily changes in certain areas.

Chrontek

A sinister organisation called Chrontek hacks into Shiro’s machine and pursues its own plans for the flow of time. As your character enters Shiro’s lab and follows the Time Tenshi through time, the story combines futuristic action, humour and fanservice, while the girls face Chrontek’s attempts to change history.
