Kii is a exceedingly skilled valkyrie who also has a talent for magics. She is also Emperor Zol's wife. With remarkable charm and amazing acrobatic abilities, it was natural that she became popular among the people for strength and looks alone. She loves making friends and isn't shy about giving people hugs of varying strengths. The strength of her hug is an indication of how close of a friend you are to her, but few people realize that. Kii also has a big heart for helping people in need during her life. She was such a remarkable fighter that she even caught the attention of Emperor Zol, which eventually led to their marriage and the birth of Nillor and, later on, Liliac. Kii is a bit of a trickster in addition to her other aspects. Typically her little pranks were nothing more than misplacing an item or object of someone's or leading them the wrong way. Of course she has done pranks involving convincing someone to dance, causing someone to do something silly or even making someone break out into song. This talent winded up becoming extremely useful one day while the royal family was investigating the danger zone and encountered the Kraken. In the attempt to escape from the creature, Kii was lost to the sea while the rest of the family escaped. Kii had died standing her ground and protecting her family. However, she had a trick up her sleeve. Kii utilized her magics to hide her spirit within her aura. Having had her soul seemingly disappear without a trace, the Soul Reaper couldn't locate it let alone send it to the realm of the dead. By the time her aura had dissipated, exposing her soul, the reaper had already moved onto other pending deaths. This was not all to her spell, as she had also enchanted a keepsake of hers so that her soul could resonate with it and grant her reason to remain in this world. This partially succeeded, she was allowed to remain in the world. However, the pendant was lost. Without the pendant in her possession, the sea owned her spirit, making her sea bound. Fittingly, she hitched a ride with a ghost ship as it passed through the danger zone she had lost her life in. She immediately fit right in and found joy right after, finding that she could easily become friends with the ghosts on board. She became captain of the ship within a month, although this was caused by the former captain mistakenly stepping on land. He was taken deep to sea shortly after. Kii is now the charming captain of the ghost ship and her ghostly crew. Should Kii obtain her keepsake, she will be able to travel anywhere in the world. No matter where she winds up being, she will be well known among the sea of ghosts.
In more recent events one of the ghosts she was friends with found out that Senka had found the pendant Kii sought out. Some of her crew, the portion allowed on land, set fourth to request the pendant from Senka. Regrettably, being ghosts and undead beings, they succeeded in scaring Senka away rather than obtain the pendant. Eventually, in Delvanos, the next opportunity opened up when the Skull Crew's ghost ship was parked at one of the docks on a foggy night. This time it was the singing and dancing Kii loved so much that drew Senka and her friend onboard. Kii, having a talent for looking just like a living being and appearing more solid the more moonlight there is, managed to approach Senka in a less fearful way. She was able to obtain the pendant she sought this time ... and of course she was able to make a few more friends.
