Raku and Tanbo form an inseparable duo. Raku comes from the same family of summoners as Itsuki, but unlike traditional summons, Tanbo is neither a warrior nor a majestic entity. Instead, he is a mischievous, cunning, and playful spirit, always by Raku’s side. The two wander everywhere, constantly on the lookout for good deals… or trouble. Their unique bond defies tradition, as they prefer instinct over rules, much to the concern of some elders within their family.
