Renka (蓮華) is the eldest of the three Mikagura Sisters and has the spirit of a true Tokyoite. She makes her playable debut in Senran Kagura: Estival Versus. She and her sisters helped revive Ryōki, Ryōbi and Ryōna's older sister.
Renka has brown hair in a twin-tails with a cowlick in the shape of a lighting bolt. Renka has the generic morphology shared between most characters in the series. She wears a brown-red long-sleeved top with a matching mini-skirt and boots. She wears knee-high socks with golden bows and a double-tail cape.
While sometimes strong-minded, her sex appeal remains prominent. She is a very energetic girl that dislike effeminate and cutesy things and, if there’s a commotion somewhere, is prone to butting in and raising her own brand of hell. No matter how tense a situation gets, though, she has a sense of humor about her and uses her laughter to break across to the other side. She has a simplistic way of thinking events and problems, making her a bad advisor when it comes to them: she always suggests and apply the solution with the less reason, making the problem worse.
She is the eldest of the Priestess, and like her younger siblings, she was educated in a secluded traditional village, the same one that Naraku comes from.
Through, she happens, with her sisters, to play frequently with a stranger girl, slightly older than them, in a white cult dress, and with several red ribbons around her hair. They play with her even if the village has forbidden contact between them and the outside world.
One day, while playing, they asks the stranger girl if she is a shinobi, to which the girl responds that yes, she is some kind of, but has a particular destiny, and another day, she asks them to warn the whole village: a monster is coming tonight.
Fearing the reactions of the elders about their source, and don't seriously believing the warning, the Mikagura do nothing of it. And they're almost going to regret it.
When night falls, and the whole village is sleeping, the Mikagura are woken up by sounds of combat: A Yōma, a parasitic demon, and one of the kinds to figure "human flesh" on their menu.
They notice the stranger girl shredding the monster. They admire her strength, and try to encourage her, but quickly notice that she is tired, and annoyed by the presence of so many potential victims for the yōma, resulting in her being swallowed by it.
The Yōma, happy to have taken it's entry, and about to take the main meal, suddenly explodes in pieces of demonic flesh. The stranger girl ended it by the outside with a kamikaze technique. All the Mikagura find left of her is one of her flowery ribbons.
The girl shares most characteristics with Kagura in her first form: a small girl with a white cult dress, red flowery ribbons around the hair and a playful personality. This is also a character that only few characters know, and the Mikagura never know her, and think she was a normal young shinobi that is dead-dead, while she is actually not.
In the beginning of the game, Renka starts out serving with her fellows Mikagura Sisters to dynamise the Festival: If the guest teams don't take the Shinobi Bon Dance seriously, there is no reason for her and her sisters to arrive and to smash or just taunt some of their members. At least it was what she was supposed to do and doing at the beginning.
The longer the Festival goes on, the lesser the Mikagura try to dynamise it, and explore the island to find Kagura, thinking her as a deceased shinobi. They keep it secret, but their inactivity, and shaddy preparations are discovered by Sayuri, with the help of Ryōki. They try to arrest and discipline the Mikagura, who resist in vain. Kafuru "saves" them by telling a seems-true lie to Ryōki, that releases them as kind as she is.
