Viktoria Dahlgrun also manages to casts this spell, which she referred to as External Style "Tendō Suigetsu" (外式「天瞳・水月」 Gaishiki "Tendō Suigetsu"), by drawing a mana blade from the tip of her Device Blaue Trombe. It is not known if she is just imitating or has learned it from Mikaya.
Suigetsu probably comes from the idiom "Flowers in the mirror, moon in the water." (鏡花水月 Kyōka Suigetsu)
- In ViVid (ch.20) / ViVid anime (ep.09), Mikaya casts it against Einhard Stratos during their spar in the dojō.
- In ViVid (ch.31) / ViVid anime (ep.10), Viktoria casts the spell during her Intermiddle match against Chantez Apinion to destroy one of her Ensemble clones approaching from the back.
- Suigetsu Double (水月・二連 Suigetsu Niren, lit. Water Moon Two Consecutive) is a combo version of the attack. Together with Tsukinowa, Mikaya inflicts over 10,000 points of damage upon Miura Rinaldi in the Intermiddle Elite Class battle (group 4 first match).
- Tendō Rengetsu (漣月 Rengetsu, lit. Ripple Moon) is probably an enhanced version of Suigetsu, in which Mikaya changes from right hand to both hands wielding Seiran during the attack.
