Proximate (来是；raize) is a family debuted in BS55. Currently, the only two Spirits to be in this family are The UnidentifiedLifeform01 Schrodinger-Dragon and The UnidentifiedLifeform02 Wahrheit-Dragon. Currently in lore, they have no relevance at all. Besides their own flavor texts, which only provide very vague meanings, the lore did not mention them at all.
The Japanese name of the family, 来是, is a pun of 来世 which means "future" or "next life", and 是 which means "correctness". It is a family which can act as the opposite of Primal.
