Kamisama Minarai: Himitsu no Cocotama

Cocotama are small spirits born from objects that have been cherished and cared for by people. They wear pieces of their eggshells as underwear, a sign that they are still in training. These little beings practice mysterious magic and work hard to assist humans, hoping to one day become true gods. They secretly live in people's homes, trying to help by finding lost items-though they often end up causing more trouble than they solve.
