The "Cyber Angels" are based on both gods and creation myths of Asian mythologies, such as Buddhism and Hinduism. Their names are written in Ateji－their names use kanji, but only for their pronunciation without any regard for the meaning of the characters.
"Cyber Angel" cards rely on Ritual Summoning and then recycling Monster cards and granting effects to aid more Summon Rituals for next turn. Also having "Manju of the Ten Thousand Hands" to search for cards to further aid strong field presence.
"Benten" inflicts effect damage when it destroys a monster by battle, and can search any LIGHTFairy monster when Tributed. "Idaten" immediately recycles a Ritual Spell Card when summoned, and grants all Ritual Monsters you control an additional 1000 ATK/DEF when Tributed. "Dakini" lets the you force your opponent to send one of their monsters to the Graveyard, allows all your Ritual Monsters to deal piercing battle damage, and adds "Machine Angel Ritual" or a Ritual Monster from the Graveyard to your hand at the end of each of your turns.
"Vrash" destroys all of your opponent's monsters summoned from the Extra Deck when Ritual Summoned, inflicts 1000 points of effect damage for each monster destroyed, can attack twice that turn if she does so, and can negate a card's destruction once per turn by shuffling a Ritual Monster in your Graveyard back into the Deck. "Natasha" allows you to increase your LP equal to half the ATK of a face-up monster on your side of the field and negates any attacks directed to Ritual Monsters you control. Additionally, when "Natasha" is in the graveyard after having been properly Ritual Summoned before, you can banish a "Cyber Angel" monster from your Graveyard, Special Summon "Natasha" and take control of an opponent's monster. Much like Dakini, "Izana" allows you to force your opponent to send a card from their field to the Graveyard, but with a Spell/Trap card. She can attack a second monster in a row if she destroyed a monster by battle. If your opponent targets a Cyber Angel Ritual Monster you control with a card effect, she can destroy a card your opponent controls by returning a Ritual Monster from your Graveyard back to your deck.
