Raiden Higurashi is a demi-goddess, born to the God Zeus and the an unnamed Megami in the Higurashi Clan. She was held the position of the 10th Seat in the 10th Division in the Gotei 13, serving under Captain Toshiro Hitsugaya. After her Captain's death, and she attaining Bankai, she rose to the Captain's position. After Joel Goldsmtih stepped down as Captain Commander, she became the Captain Commander, shortly afterwards achieving her Bankai Stage 2. Over one hundred years later she bcame a member of the Royal Guard due to her creation of the hand held Sokyoku Blade; this was shortly after having achieved Bankai Stage 3. And finally, at some point after that, she was emitted into the the Holy Guard, shortly after she achieved her Omoimoyoranai Shinsou. Born to a large family, most of her siblings, both brothers and sisters, were only half siblings, except for one, her blood brother Raidon Higurashi, who was once a member of the Albatross Syndicate, before leaving and joining the Balance Breakers. Raiden herself has worked in the Gotei 13 most of her life, but has also worked with the Albatross Syndicate and the Balance Breakers for certain lengths of time before joining the Royal Guard; for over one hundred years she was considered a tratorous soul, but due to saving the Soul Society from the wrath of Honoka, (albeit temporarily), she was relieved of all of her crimes.
Starting as the black sheep of the Higurashi Clan, today Raiden is feared throughout Soul Society and Hueco Mundo respectively for her almost unrivaled power. Before joining the Holy Guard, she beat Joel Goldsmith in combat; although Haku Goldsmith assumed that Joel was holding back, Joel corrects by saying that, although he was, he still doesn't think he'd be able to win, because Raiden was holding back just about as much. Joel theorizes that, currently, in terms of enemies to the Soul Society, only Shikyo Fushiawase, Lucifer, and Honoka would have a chance at defeating her one on one, which she also acknowledges, and thus is still training for.
Daughter of the greatest of the Gods in all of Nirvana, Zeus, Raiden boasts great pride in hier linneage, but has always had as trained relationship with her father ever since ths learned the truth about her linneage, despising him for his continuous reputation of cruelty, towards both the other Gods and Angels lower than him, as well as towards the beings outside of Nirvana as well. In Soul Society, and certain parts of Nirvana, Raiden is known as the Mistress of Blade Punch, due to her almost unrivaled power in both Hakuda and Zanjutsu, (only Shikyo can beat her in Hakuda and only Nemaya can beat her in Zanjutsu). That being said, however, she has unbelievable power in both Hoho and Kido as well, not to mention the Seishin Kei, special mind-related techniques that are unique to herself, earning her the secnodary monicker Queen of Mind Games.
