I actually did it, I actually THOUGHT ABOUT WHICH SAILOR SOLDIER BELONGS TO WHICH GAME OF THRONES HOUSE (because of this post)… someone put me to bed this is nerdier than I ever thought I’d become. ;A; A lot of these houses are barely in the book, but they have sigils and mottos and that is good enough for me (you can get info and pictures of the sigils from this wiki).

Going by mottos -
Moon: Unbowed, Unbent, Unbroken (Martell)
Mercury: Wisdom and Strength (Mooton)
Mars: Fire and Blood (Targaryen)
Jupiter: Unflinching (Peckledon)
Venus: Brave and Beautiful (Piper)
Chibi Moon: Growing Strong (Tyrell) - hahaha get it (jeeze)
Tuxedo Mask: Family, Duty, Honor (Tully) - HE IS A TOTAL DAD he is all about THIS.
Neptune: I Have No Rival (Serrett)
Uranus: Let Me Soar (House Fowler)
Pluto: Ever Vigilant (Flint of Widow’s Watch)
Saturn: Winter is Coming (Stark) - Hotaru is kind of a Debbie Downer.

Going by sigils:
Moon: Baratheon of Dragonstone (Stag surrounded by a firey heart) or House Wynch (Bloody moon on purple) - This was hard because there weren’t really any MOON SIGILS other than the bloody one… and Stannis’ sigil reminds me of her Cosmic Heart Brooch. u3u
Mercury: Tarbeck (Silver and blue 7 pointed star, on silver and blue background) - It was either this or any of the ones with fish in them and Ami is too good for trouts.
Mars: House Blackwood of Raventree Hall (Flock of ravens on red, surrounded dead weirdwood)
Jupiter: House Dondarrion of Blackhaven (Forked purple lightning on black with four pointed stars)
Venus: House Piper of Pinkmaiden (Pink dancing woman with a bolt of swirling silk~)
Chibi Moon: House Brax (Purple unicorn) - HELIOS… if he were purple!
Tuxedo Mask: House Tyrell (Golden rose on green background)
Neptune: House Merlyn of Pebbleton (Twining waterspouts)
Uranus: House Dayne (silver sword across a silver falling star)
Pluto: House Toland of Ghost Hill (Ouroboros)
Saturn: House Harlaw of Harlaw (Scythe on black)

Feel free to disagree with me because this was hard and I probably missed something OBVIOUS.
