Vaigo (ヴァイゴ Vuaigo?) is the mysterious ally of Aiji's Adventures Saga and the alter-ego of Aoi Zaizen/Blue Maiden (who was Samuel Nakaoka the Second's second female identity) with KaijinFusionary of Naria and Medusa Phantom CharakCapsules.



Though she is the benevolent being, Vaigo is also merciless that someone brutally killed a person and taunting or tortures someone else as she watches everything; in this case, Millaarc killed a girl and taunts Tsubasa and Vaigo arrives and brutally tortures her by using several enemies.


As Vaigo, she used the upgraded variant of Zi-O Driver called V/aI-O Driver to transforms into her Ranger Form. When she used her V/aI-O EVOwatch, she combines any CharakCapsules and/or Ridewatches to transforms into EVO Ranger form.
