If we look at Mika’s role in granblue — the “radiant, almost idol-like” figure hiding deep manipulation and a morally gray agenda behind a charming front — the closest grub comparisons in plot and story beats would probably be:

Lucilius – A charismatic visionary with a god-complex, whose “grand plan” has both idealistic and dangerous edges.

Belial – A smooth talker, playful yet calculating, who manipulates others for his own goals while hiding a deeper obsession.

Sandalphon (early arc) – Someone burdened by personal vendettas and complex loyalties, balancing angelic image and inner turmoil.

Zooey (original) – The “chosen” or “symbolic” figure tied to cosmic balance, whose existence is wrapped in grand stakes.

Narmaya (event-based parallels) – Though not identical, certain event arcs show her as a beloved figure whose personal struggles contrast her public image.

If I had to distill it, Mika’s granblue narrative vibe is a fusion of Lucilius’s ambition, Belial’s manipulative charisma, and Sandalphon’s conflicted savior role.
