Miyu being obsessively in love with Illya while her third skill makes her see anyone - male or female, human or monster - as her feels designed for degen doujin plots.
The fattest, ugliest, bastardest dirty oji-san could walk by and Miyu might see him as Illya. Wanting nothing more than to passionately kiss him anywhere, and listen to any request he has of her.

I have 30 quartz and a dream when Miyu drops tomorrow. I haven't had a 4* in the last like 500-600 quartz i've rolled so I feel very overdue.
