An adult Chen-type. It has no limbs or torso, only a head. Its species is Yukkuri, a living manjuu. It has brown hair, cat ears with a piercing in the left ear, and two tails like a bakeneko. It wears a green nightcap-like hat as its 'accessory.' Its eyes are brown. It refers to itself as 'Chen' and speaks with a characteristic drawn-out tone, ending sentences with 'dane-.' They are honest and easy to bond with, making them suitable for pets. However, they are very active and move around a lot, so it is best to provide space for them to run. Chen-types seem to find 'Yukkuri' (a sense of happiness and fulfillment) in running around and are not good at staying still. This one is a parent Yukkuri, about the size of a soccer ball. Its catchphrase is 'I understand,' and it frequently says, 'It's [blank], I understand.' It calls its child 'Little One' and refers to humans as 'Mister Human.'

A baby Chen-type. Like the parent, it has no limbs or torso. It has brown hair, cat ears with a piercing in the left ear, two tails, and a green nightcap-like accessory. It is palm-sized and very small. It is curious and cheerful. It does not understand irony or sexual concepts. It refers to itself as 'Chen' and speaks with a drawn-out 'dane-' tone. It is honest and easy to bond with. Because it is active, it needs space to run around. It finds fulfillment in movement and dislikes being still. It calls the adult Chen-type 'Mommy' and says things like 'I'm sowwy...' when apologizing.
