There's also "two" Valkyries: one during the assault on the Monster Lord's Castle, and another in Grand Noah on day 3.

Imp was quickly unsealed because she's extremely low leveled; she doesn't need to accumulate a lot of power to regain her form. Tamamo could unseal the two-tailed Kitsune, but she couldn't do the same with Nanabi at the same time. The difference in power between a low leveled monster and a 9th Circle Angel is quite vast.
