"Starlight Honeymoon Therapy Kiss" is an powerful moonlight-based attack performed by Eternal Sailor Moon in the manga, 90's anime, crystal, and musicals with her Eternal Tiare.
Manga and Crystal[]
Dream arc[]
It is first used after Usagi becomes Eternal Sailor Moon with the power her friends directed to the Holy Moon Chalice. Usagi asks her friends to gather their power into her Eternal Tiare. The Sailor Princesses call upon their Sailor Crystals, which lets them take their own Eternal forms, along with Tuxedo Mask who unseals his Golden Crystal and offers its power. Eternal Sailor Moon uses the gathered power of her friends to perform Starlight Honeymoon Therapy Kiss to obliterate Queen Nehalennia and end the curse of the Dead Moon.
Stars arc[]
In The Secret Hammer Price Hall, Eternal Sailor Moon and Eternal Sailor Chibi Moon perform a duo version of the attack called Starlight Honeymoon Double Therapy Kiss to save Hotaru.
Throughout the Stars arc, Eternal Sailor Moon uses the attack against Shadow Galactica. Its final use is in Galactica Palace against Eternal Sailor Venus who blocks the attack and mocks Usagi for the apparent weakness of her Silver Crystal and counters with Galactica Planet Attack.
Anime[]
Sailor Moon finally taps into this power when all the Super Sailor Senshi lend their strength and abilities into Super Sailor Moon's brooch, evolving her into Eternal Sailor Moon form. It was used mainly to heal a Phage and return it to their human form by using a healing command which unleashes several blasts.
When Sailor Moon used this attack in the anime, the Eternal Tiare appeared with a flash of pink light, then producing streams of rainbow-colored light from the crystal at the top of the Tiare. It began to spin fast and she appeared behind it, hands outstretched to guide the spinning Tiare above her head and then in front of herself once more. (Beginning in episode 176, there was the addition of feathers that flew across the screen as the Tiare moved above her head.) She then grabbed hold of the Tiare with her right hand and light flashed. She called out the name of the attack as she spun around, holding the Tiare above her head, and on the final word raised it high in the air with both hands. Pink light flared at the top of the Tiare and streamed toward the target in multiple waves; if the target was a Phage, a torrent of feathers would also rush past it, then the Phage cried out "Beautiful!" before returning to his or her normal state.
In the Dead Moon arc of Sailor Stars, it was used offensively to destroy the Mirror Paredri sent by Queen Nehelenia, although it was unnamed. Chibi Chibi helped it grow into Silver Moon Crystal Power Kiss in episode 187.
