Kikaijikake no Ai: Mamajin

Mamajin, the mother robot who gathers together orphans and raises them as a family, is kind, but has no heart.

She's a good cook, but has no sense of taste. The children bond with Mamajin, who is a little clumsy but powerful and cute... A heartwarming and delicious story of a family.
