"
Gishki", known as "
Ritua" (
Richua) in the
OCG, is an
archetype of
WATER monsters released in
Duel Terminal - Raid of the Inverz!!. Their team symbol is a
blue sapphire mirror, that almost all the members wear, usually around their necks or on their staves.
The
Ritual Monsters and
Xyz Monsters in the archetype all have "Evigishki" at the beginning of their names (except "
Zielgigas" and "
Psychelone"), and are transformed, merged or revived versions of pre-existing monsters, either from the "Gishki" themselves, or from other archetype. Additionally, while the "Gishki"
Ritual Spell Cards can Ritual Summon any "Gishki" Ritual Monster, each Ritual Monster has a thematically associated Ritual Spell Card.
