ネコアルク

Neco-Arc is a member of the NEKO Spirit race, originating from the Great Cat's Village. It's either a materialization of TATARI or the guest from another world brought here by Zelretch, as well as the mascot character of Type-Moon.
She speaks with the catlike accent and likes to play on the nerves of others. Even her appearance frightens certain characters.

Present in Tsukihime Remake, but only in After Bad End scenes.
