Nope, it's having a deep interest in Lilian, and I THINK have got the first sigil. When you talk to Lilian about the church, you get a series of things to ask her. You'll need to ask about the good luck handkerchief twice, because there will be a new set of options, and then ask "does it really work?". Have to ask about monster girls a few times too, to have you comment "um, you do know how fighting is done here?". Ask if she's OK when it pops up.
Ok now I know how to make the event appears.
You need have to talk with Lillian (and those options you mention) and talk about other people around(Elena, Elly, Vivian and Amber, Lucille is unnecessary).
All your stats 10+
Have at least 1 sigil and talk with Lillian when you have the sigil.(Then left the church and just enter again if you have all of this things to make the event)
Skills are unnecessary.
I know it's not based on skills, because there's a bunch of skills I hadn't purchased and still get Demon Layer. Don't THINK it's stats based, but honestly wasn't paying attention to that when I get it. Deep interest in Lilian and one sigil doesn't sound right though.
Some of Lilian's answers are definitely funny!
I think is stats based because this were my stats to make the event appear.
One point: I never spend points in power when I completed everything my power was in 3 (with the Sigil of Power and some perk IDR) . Then when I increment my power (to learn Elena's skills) I incremented until 20 with runes, accesories and blessings and enter to the church the event appeared.
Thats makes me wonder how to make this event appears right now when I complete everything.
