In the Luna VI: Melting Moonlight in the Morning Mist only three humans who can withstand the kuuhvaki blood transfusion can enter the portal
Traveler, Arlechinno and Lauma + Nicole who serves as a guide

But then why is Paimon in the quest as well?
She explicits says that she will not do the 3 day no food/water diet. But there she is
I undestand Paimon serve as a guide and in the most part of time, as a way to explain lore to the player. But it just ruined all the immersion


Is there a canon explanation?
Why's Paimon in the Luna VI portal quest?
