Gleam evolves from Chansin when fused with a Holy Blade.
Gleam looks similar to that of Sheen, but his hat is gold colored (along with a small golden fire atop) with several green beads underneath it. His scarf is red, the sword is sky blue with the sheath being light yellow colored, his hakama is orange, and his sandals are yellow.
Fuse the Sublime Whetstone and the Battered Blade to obtain a Holy Blade for Chansin. You get the Sublime Whetstone from the Oni Crank-a-kai while you get the Battered Blade for 600 Jungle Points at the Jungle Hunter.
Another way of obtaining Gleam himself is using Glitzy or Cheerful Coin in the Crank-a-kai, or after clearing Terror Time with the Oni Crank-a-kai in the Yo-kai Watch Blasters Mode.

Gleam's Japanese name, Kusanagi, refers to the sword of the same name, one of the Three Imperial Regalia, originally named Ame-no-Murakumo-no-Tsurugi ("Sword of the Gathering Clouds of Heaven"), which the warrior god of storms Susanoo had carved out from the tail of the slain Yamata-no-Orochi (see Venoct#Origin) and gifted to the goddess Amaterasu as an apology gift for his past misdeeds. It was later given to the legendary hero Yamato Takeru.
One day an enemy warlord lured the hero into a trap while he was hunting on an open grassland, launching a volley of fiery arrows that set it ablaze. Desperate, Yamato Takeru used the sword to cut a path through the burning grass, and in doing so discovered it had the power to control the wind in the direction it was swung. With that newfound ability, he pushed the flames back against his enemies and turned the tides in his favour. In celebration of his victory, he renamed the sword Kusanagi-no-Tsurugi ("Grass-cutting Sword").
"Gleam" means "to shine brightly".
"Glitza" is a corruption of glitzern, meaning "glisten".
