[Miraculous Fish Tank] Recall the Memories

This tale... It reminds me of the shellfish I gave to my father when we visited the seashore... Its color is so beautiful that I wanted to give it to him. Could you find that shellfish and bring it to me next time? I believe it would help me reminisce about our memories. I'll reward you with a special item I've created using the power of the Netherworld. However, to safely handle the item I've made, you need to be somewhat proficient at fishing.

The story reminds me of the time when I visited the seashore and collected shellfish with my father.

Here it is, the special item I mentioned. Looks like an ordinary fish tank, doesn't it? But this absorbs all the surrounding light because it is imbued with the power of the Netherworld. And time within flows at a significantly slower pace so that fish inside stay fresh much longer. You helped me bring back memories of my father, so... This is the least I can do. Thank you!
