I see plenty of people around with Nasuverse-related avatars, so I think it would be reasonable to have a place to discuss this multiverse.
For those who don't know, the Nasuverse is the multiverse which includes all the works of TYPE-MOON's Kinoko Nasu. These works include, but are not limited to:
Tsukihime series (Tsukihime, Kagetsu Tohya, and Melty Blood)
Fate/ series (Fate/Stay Night, Fate/Zero, Fate/EXTRA, Fate/EXTRA CCC, Fate/Unlimited Codes, Fate/Kaleid Liner Prisma Illya, and Fate/Apocrypha)
Kara no Kyoukai
Mahou Tsukai no Yoru
Canaan
DDD
and others.
