The genie walks without a sound

Exploration Stage: Wonderful Cat Cafe
From: Hanako
Description: We need to prepare the cat café for the meeting with the eternal cat. The funnel is getting bigger and we must protect the spirits from its influence. I will place a ward at the summoning point. Can you get an artifact so that I can accumulate magical power in the warding?
Completed: All went well! As the protective wards unfolded to cover the welcoming tatami mats, the eternal cat appeared. These spirits liked our gift and gave us the artifact "Heart of Harmony"!
