The protagonist who fell from the sky into the Sun Kingdom and lost their memories. A lost child who somehow always gets caught up in trouble... They decide to join the Guardians to protect the kingdom's "Cuteness"!

A Hoppe-chan with distinct, slightly timid eyes. A cautious opportunist (and a worrywart) who finds it hard to take action. The flower item on their head can spin, allowing them to fly through the air.

A Hoppe-chan with odd-colored eyes and twin tails who possesses a rare "star quality?" A bit of a ditzy troublemaker because they are constantly chasing the meaning of being a "star." Their core motivation and judgment criteria are always based on "star quality."

A Hoppe-chan who is a bundle of intellectual curiosity. They are more curious than anyone else about Ganso-chan's origins. They are the top theorist among the Guardians.

A self-proclaimed princess-type Hoppe-chan with a tiara item, who is an unconscious masochist. They have cross-shaped stars in their eyes, which are proof of celebrity status in the Sun Kingdom. While they have leadership qualities among the Guardians, they are as much of a troublemaker as Star.

A Hoppe-chan who speaks slowly and elegantly with a Kyoto accent. Their deep kindness is reflected in their perpetually closed eyes... but watch out if their heart item turns upside down! They enter "Spade (Anger)" mode and start ranting in a rough Tokyo dialect.

The King of the Sun Kingdom. A large-bodied Hoppe-chan who shows his dignity with a mustache and a crown. He tends to turn a blind eye to the kingdom's unrest and gives the Guardians haphazard orders. He thinks anything is fine as long as it's cute, but he might not actually understand the essence of cuteness!?

A black Hoppe-chan born in the turbulent Sun Kingdom, influenced by the Reborn Machine. To change the Sun Kingdom, which is dominated by values of pure cuteness, they formed the "Black Hoppe Gang (KHG)" as the leader alongside Yami-chan and Doku-chan. The fangs they show when plotting are quite cute.

The strategist who supports the Black Hoppe Gang's intellectual battles. They adore the leader but are so blunt with their critiques that the leader often feels like they're just being insulted. They have zero respect for the Guardians and will say brazen, annoying things without hesitation. The pink twin tails and the eye patch with "Darkness" embroidered on it are a charming color combo.

The vanguard of the Black Hoppe Gang, a black Hoppe-chan with a "Poison" mask and a mild delinquent vibe. Even other gang members fear them as a "mad dog"!? They express themselves with the single word "Poison" and follow up by holding up placards with comments or emojis that match their current emotions. Has a habit of dozing off.
