In the first episode of the Chinese-Japanese anime collaboration 一人之下, we see Zhang Chulan (张楚岚) in a classroom at his university. Just prior to this, we see a still of a university building, with a plague that appears to read (left to right) 南不海大学.
This struck me, at first glance, as an implausible combination of characters: I could not think of any reasonable reading for them. Moreover, my sense is that 不 only makes sense attached to a verb (他不说德语) or adjective (这份功课不难), unless it is attached to 是, in which case a noun can follow (这本书不是罪与罚).
Is my intuition correct, or is there actually a plausible reading for this sequence of characters?
