Jikuu Tantei DD 2: Hangyaku No Apsalar

In 2231, a detective unit in Bangalore is dispatched to investigate a strange alien artifact at the Apsaral Center. The artifact activates during the investigation and detonates a dimensional distortion bomb, destroying part of the building. The organization managing the operation makes the coldly pragmatic decision to write off the agents caught inside rather than risk an alien infestation. Five years pass. It is 2236 now, and in a private detective office in Japan, one of the two agents declared dead in Bangalore is still working. The case that ended her official career five years ago has never been formally closed. She is going to close it.
