the "perhaps waiting for the second hundred" makes me think of the lighning dodging.

Does it have anything to do with Lulu's Onion Knight?

lying hidden near the demonic, (find it after killing Geosganeo)
maybe seeking, maybe hiding, (it's hidden...not sure about the seeking part)
perhaps waiting for the 2nd hundred, (as mentioned, the lightning dodging)
i take only 1, but give more than the usual (not sure about this line)
who am i?
