In Misawa's first mission, second objective (Update 17, Video 33) we were supposed to stop off and pick up a box of lightbulbs in one of the apartments on the way up to the roof to shoot Okita. I forgot to do it in that video, but picking those up was required to unlock this stage's secondary objective.

The keukegen is a vile monster covered entirely in long hair and preferring to dwell in dark, damp places. It is said that the creature infests some homes, stealing the life of the inhabitants, causing them to fall ill.
Sightings are exceedingly rare, hence the tendency to call such occurances "Bizarre Sightings".
(NOTE: As far as I can tell, "Keukegen" isn't a real word, but a parsing of the kanji suggests it means something like "Fluffy-Feathered One".)
