Sure, if it's the 2nd CE for Licca she needs some Cocoon maiden materials. One is a rare, and the other two are relatively common. Go to a mission that has 2-3 of this Aragami and do it 2-3 times and you should have the required items in your inventory if you devour all defeated corpses.
yup i have it.. 1 is kinda rare like what you said and then 2 of the other one.. i saw a video on youtube where licca stands beside the merchant but in my game she's still standing in front of the gate..
Hmm if Licca stands in front of the gate that doesn't really change much.
She is there because the story advancement is different from yours, or you "summoned" her with the help of the Character Episode menu. It's quite nice, since that way if an NPC has an available CE, but isn't present during the actualy part of the story you are currently at even if they would be available.
You can just call on them, and get done with the CE... Took me a while to figure that out myself as I can't read the moonrunes :V
Hmm, Once you give the items to her the Episode is actually finished with some talk.
Check the Character Episode menu inside the terminal and see it's current status.
And... I am very aware that it's in Japanise, but you can just compare it to someone elses Character Episode listing that is either "completed" or "not yet available", since if it's still ongoing then it would detail what Licca wants.
