Holy shit! Chiaki was a real student after all! They made her out to be just the guardian program of the hope restoration program, but I guess Chihiro based her on one of their classmates (who is probably dead since she wasn't with the other Remnants of Despair in DR2, at least physically). Also her words to Hajime and their budding relationship explains why she alone was able to reach him in end of DR2 to turn away from the person that Hope's Peak Academy made him and turn to Hope. Also apparently Housekeeper lady that was in DR3 Hope Arc was their teacher and very curious as to what she meant by "seeing herself die a second time" means at the beginning of the narration of the prequel. Also the headquarters of the Future Foundation was the overseas Hopes Peak Academy they were building so obviously Hope Arc will be going through another HS.
Also bitching to see the whole DR2 cast acting their zanny selves again, this time animated, really grew attached to the cast after midway through DR2. Looking forward to this Arc more then Hope tbh, very curious to see how Junko warps them into becoming her Remnants of Despair. Also really loved the Opening, think it fits much better then the Opening for Hope Arc.
