There is speculation among Japanese fandom that butterfly is a disguised "Holy Grail" used by Demon Pillar to 'lock' Shinjuku as its territory. The reason is because:

1) Its the only remaining 'colored place' in Shinjuku,

2) It located near Baal, implying its related to how they realize their plan;

3) The leitmotif is 'blue butterfly' that often used to symbolize time and wish-granting.
