Slay is human and Mikurio is of the Family of Heaven (or Tenzoku—we’re without an official translation here), but both were raised together from infancy. They understand they’re of different races, but have never took much notice because of Slay’s high spiritual power to always see Mikurio.
Normal humans can’t see those of the Family of Heaven. In fact, with the exception of Slay, Alicia is the first human Mikuro is faced towards.
Slay is freehearted, while Mikurio is the calmly considerate type. They’re a good match because their relationship is complementary. The pair often argue over Slay’s archaeological interpretations.
The Family of Heaven is a mysterious tribe discussed as an object of faith. They exist as pure beings that dwell within material “vessels,” and can manipulate nature through “Heaven Echo Artes” (Tenkyou Jutsu).
Only people with a strong spiritual power have the ability to see and interact with the Family of Heaven, therefore they signed a contract to become their vessels. These people are called “Monks” (Doshi). These Monks could use the power from the Family of Heaven freely, but their existence, along with the people from the Family of Heaven who could hand down this knowledge, has been long lost.

A rival and close friend of Slay’s from the Family of Heaven. Since their infancy, the two were raised together in Izuchi. As Mikurio and Slay would play inside the ruins, Mikurio himself also took interest in them. He plays a role in calmly pointing out Slay’s erratic behavior, and often argues with Slay about his archaeological interpretations. He can use Heaven Echo Artes, which take on the water attribute. Given that Slay has the spiritual power required to see members of the Family of Heaven, he is able to see Mikurio. Alicia, however, cannot. Members of this divine family have been given a near-ageless lifespan.
Additional images come via Famitsu scans, courtesy of Tokkurin. You’ll see Slay with his white coat removed, as well as the Mabinogio Ruins dungeon.
The ancient Mabinigio ruins have maintained their original structure without damage from weathering. Some of the ruins are connected as far as Izuchi, and since their childhood, Slay and Mikuro have pushed forward in exploration.
Tales of Zestiria is in development for PlayStation 3.
