I played book 4 again just to trigger Ikki scenes on this epilogue, and I'm sure that I triggered all of them until now, at least every possibility I could find, got some scenes, but during first day of the spirits festival I talked with Shady about having some other girls during the third day, and I could suggest some names, I chose Ikki and... nothing else happened then. Did MITY forget about this possibility? Or just abandoned the idea? Since Ikki scenes are not written in the changelogs, idk if I missed something.
