The kanji in their Japanese names literally translate to "Light Angel", fitting to both their Type and Attribute.
Each member's name is also an alliteration of the letter S.
Similar, but inferior to the "hunder" archetype, two of the three monsters Normal/Special Summon other "Star Seraph" monsters, swarming the field. All "Star Seraph" monsters are Level 4 with slightly different effects as "hunders". With "Star Seraph Scout", when Normal Summoned, you can Special Summon another "Star Seraph" monster from your hand. The effect of "Star Seraph Sage" has you discard a Spell from your hand to Special Summon another "Star Seraph" monster from your hand. While the last monster, "Star Seraph Sword", instead of being able to Special Summon, it sends a "Star Seraph" monster from your hand to the Graveyard to increase its ATK until the End Phase. Adding in "Nova Summoner" is a great idea since when it's destroyed, you can Special Summon a LIGHT Fairy monster with 1500 ATK or less. It proves to be a much better option than "Shining Angel" since his effect leaves your Life Points open due to Special Summoning your monster in Attack Position.
