In order to counter her Partner's rather strange mannerisms, Lightning has adopted a rather over-the-top attitude, although she doesn't do it entirely without fun. When she adopts this trickster facade, Lightning certainly stands out amongst her peers, both old and young. As this Lord was completely Feral, she was not properly trained in the arts of Lordship. Thusly, while she has a unique way of fighting and using her magic, she is not a 'refined' Mistress. Still, she doesn't seem to care about this supposed 'setback', and "keeps on trucking" everyday, no matter what.
Lightning is someone who loves to see others react in a "cute" or happy way. Therefore, even if it's at the expense of others, she'll often over-compliment people to the point of a meltdown or an overcharge. Though she's able to bring out this natural positive energy in others, one can sometimes find Lightning sulking in a corner if things become a bit too lovey-dovey (as she misses Kaito dearly). However, even if she is incredibly playful, she'll never act to harm any of her friends or close ones. Though, she might act a little more strongly if she wants to see the reaction of another person, friend or not...
In terms of fighting, Lightning fights with a lance. Showcasing excellent balance, she's nevertheless one of the weakest fighters on the team, holding the record for the lowest stamina of them all. Though she fights in easy-to-move-in clothes, and with her forte nearly every time, Lightning simply does not like to battle often, and it shows in her stats. She would much rather prefer to enjoy her time, and maybe create a new piece of glass art in her spare time (though sand is hard to gather for her). Still, her magic isn't something to be trifled with. Able to act as a literal Lightning Rod, Lightning can absolutely destroy numerous enemies at once with her powerful Thunderblasts and Bolt Beams.
She doesn't mind Takuto too much. Teasing him is mildly fun, but Lightning is much better friends with her 'nephew', Mikage (who in actuality is 2 generations younger than Lightning...but the time rift as a result of Takuto's summoning spells has messed some things up anyway).
Ever since Ragnarok's Call has passed, Lightning has retained some of the energy she showcased amongst the group, although she and Kaito have eventually mellowed out together. Though they're still very fiesty at times, they both show an undying loyalty and love for one another. Now that she's good friends with Takuto, who is many generations her junior, she might have influenced Takuto's charm abilities a bit herself...
She and Kagetora are cousins.
Before the Clan was made, Lightning fulfilled her dream of becoming Crysta's Mate, and was much flirtier than usual afterwards as well. When the Clan was created, after Crysta returned from a visit to Ceres, Lightning invited her to celebrate with her, and gave Crysta the gift of a Thunder/Love Core, a gold necklace and a yellow topaz ring filled with Thunder Magic. She then revealed her unusual ability to make Cores as well as the usual Seeds, and gave Crysta her own Core in the promise that they'd Soul Bond one day. Lightning seems ecstatic to finally be a mother, though she does show a bit of confusion over whether she counts as Raiko's mother or not due to her unusual way of coming to life. Nevertheless, she seems extremely happy to finally get the chance to be a parent herself.
Now that Lightning's had another daughter (who stays with Crysta as a summon) and a son, she seems to be much more confident, and has fallen into her playful ruse legitimately. Though she's still shy at times, with Crysta and her family around, they're becoming much harder to spot.
While visiting Lovcore, Lightning gained 2 new Mates, the first being Coba (a small creature she keeps safe within her pouch) and the second being Rahlo, a very affectionate wolf. She seems to enjoy both of their presences quite a bit, and takes great joy in playing with them from time to time.
After a rough breakup, Lightning decided to forgo dating and has decided on focusing on improving herself and taking care of Raiko, hoping that someday, she'll be able to make both herself and any future partner she may have happy. She's grown closer to Black-bell as a friend, fortunately, so it seems her attempts at self-improvement will go well. She seems to have a crush on his elder sister, Blue-bell, though.
An older reference of Lady Kaito and Lightning. Apologies for the somewhat awkward reference (it's all I've drawn so far. I'll draw another one sometime). Lightning is the blonde, as you can see here.
