I came across the sentence 「宇宙KOMAなりき」in a Dragon Ball song. The context is like this:
回り磁極踊れば 大地も空も 世界は巡る 宇宙KOMAなりき
The song lyrics are here: http://www.kget.jp/lyric/112532/KOMA_CHIHO
What can possibly mean なりき? My first guess was that it came from a verb (なりく？？) or be a な+Noun pattern. Or even なり＋気. What do you guys think?
