Emilia is the main heroine and deuteragonist of the Re:Zero kara Hajimeru Isekai Seikatsu series. She is a half-elf and a candidate to become the 42nd monarch of the Dragon Kingdom of Lugunica in the Royal Selection, who met Natsuki Subaru on the day he was summoned to the world. Emilia has played a supporting role in every arc, with major and pivotal roles in more than half of them. Born and raised by her aunt in Elior Forest, Emilia is a half-elf terribly beloved by the spirits. However, during the Permafrost of Elior Forest, her memories were locked away, and she was frozen for approximately 100 years. After being watched over by Puck, she eventually became a Royal Selection candidate in the hopes of unfreezing the residents of the forest. Through many trials and tribulations, including mass discrimination, she came into her role well, holding many feats under her belt, including helping to defeat the Sin Archbishop of Greed and the Great Rabbit, becoming the administrator of the Pleiades Watchtower, and forming an alliance with Vollachia.

As a member of Inherit, Harran also wanders the surface, fighting off Raptures, but for her own interests rather than something grand like "duty to humanity." Harran's belief is one of survival of the fittest; the strong can live as they please, whilst the weak can only try to curry favor from the strong. Fancying herself a "predator," Harran stalks the lands in search of things to further her beauty, being incredibly absorbed in polishing her own radiance. In fact, one way to curry her favor is to acknowledge and exult her beauty, and follow her orders with little complaint. A number of Harran's brews, be it food or cosmetic, seem to be derived from ancient texts of witchcraft. Harran views herself as an apex predator on the surface, caring little for humanity and their aims to reclaim it. In fact, she despises most humans for how deceitful they are. To her, only the strongest are able to survive and they are the only ones who can do as they please. Her role in the food chain combined with her beauty has led Harran to being a narcissist who views herself above most others. She mostly travels across the land to slay Raptures and to make herself more attractive. Despite how self-centered she is, those who are able to placate her, whether by following her commands or stroking her ego, tend to be able to end up in her good graces. Harran usually cares for those who treat her well.

Yae Sakura was a miko of Yae Village. Despite her devotion, hard work, and wishes for the village's well-being, her ill sister was ultimately sacrificed and used in a barbaric ritual to try and bring rain during the droughts. Despite her sister's last wish to not let fate burden her, Sakura gradually began to feel hatred towards the village. Yae Sakura was born in Yae Village, Shinano, Japan, to the Yae family, and had a natural stigmata. She also had a younger sister by the name of Yae Rin who was often sickly—a stark contrast to Sakura herself. Thus, she made it her duty to take care of Rin, and the two were practically inseparable. That was until, a drought plagued the village, prompting her father to choose to sacrifice Rin. Unwilling to part with her sister, the young Sakura made plans to escape with her sister out of the village. However, her father discovers this and has the villagers hamstring Rin prior to the actual ritual. When Sakura was called up to deal the final blow, she cut Rin's bindings and tried to run, only to realize that Rin could no longer use her legs. Her father then grabbed her hand and drove the blade through Rin, while Rin's last wishes of "being a good miko" will haunt Sakura for years. When Sakura was younger, she had an unshakeable will to do everything possible for the sake of her younger sister. At a young age, she was already burdened with the layers of responsibilities and handled them well, finding satisfaction in her duties, especially concerning her sister. However, after Rin died, Sakura's world shattered, and she became cold and detached, performing her newfound duties with diligence and grace as a miko simply because of Rin's dying wish. It was only until she met Kallen, did she start to hope and feel again, for something she wanted to protect in this world.

Veliona, also known as Seele Vollerei (or Starchasm Nyx). A being awakened inside Seele Vollerei, originally referred to by the latter as "the other me". She's related to the stigma Seele has on her chest and vowed to protect the frail girl—the meaning of her existence—from all harm that should come her way. Acts violent, cruel, and occasionally even sadistic to her enemies, but is straightforward in conveying her genuine feelings of goodwill to those she cares about. Still, she prefers fighting and violent solutions to solve problems, especially to protect Seele and her friends. Dislikes books and easily fall asleep while reading. Proved herself to be a bit of a prankster when she swapped out the ketchup for a spicy chili sauce she liked which Sin Mal in turn hated. More recently, it has been shown that Dark Seele is actually anxious, pessimistic, and has low self-confidence, as noted by the Herrscher of Sentience. A being born from the desire for protection, her identity revolves around being Seele's protector. As Seele continues to grow more independent and mature, Dark Seele is starting to lose her sense of self. She's anxious about being forgotten by Seele, fearing that she will get left behind in the future, therefore she still clings to the fact that Seele might still need help once in a while. She holds Seele in high regard, viewing her as everything that she's not; gentle and caring, someone that everybody likes. This in turn makes her view herself negatively and if Seele's friends find out who she is, they will dislike her thus making her even more withdrawn from Seele's social circle. Since she only knows how to solve problems through fights, she's clumsy and socially awkward especially when dealing with Seele's friends, particularly Bronya Zaychik and Kiana Kaslana.

Raven (originally named Natasha Cioara) was born in Siberia. Following the Second Honkai War, in which she gained strong Honkai resistance, she was selected by the Gray Serpent and was forced to leave her brother behind. Natasha received training and became a mercenary subject to the World Serpent. In 2000, when the core of the Herrscher of the Void was out of control, a huge amount of Honkai energy overwhelmed the entirety of Siberia and caused its people to become corrupted. Thanks to the sacrifice of Cecilia Schariac, most people, including Cioara and her brother, had survived under the protection of the Holy Blood of Schariac. However, Cioara gained resistance to Honkai and was taken away by the Gray Serpent, and was trained as a combatant of World Serpent. Her appearance underwent many changes during that time and she'd be given the codename "Raven". As a mercenary, Natasha is a practical individual with a no-nonsense attitude, who believes in a strict work ethic in which a job is a job and must be accomplished to its fullest in spite of any personal reservations or dangers to herself. Befitting of a mercenary, Natasha holds no true loyalty to any cause or faction besides whoever's paying top dollar—which most often happens to be the very organization that raised her. Natasha also holds a great sense of respect for the Sire of World Serpent. Natasha has been shown to have a penchant for dry humor, fine alcohol, and the occasional philosophizing. But perhaps the most surprising part of this ruthless mercenary is her caring nature, possessing a soft spot for children displaced by the Honkai with nowhere to go, much like herself when she was taken in by World Serpent. Natasha takes in many such children under her care and tutelage, and although she sees to it that they are taught how to survive on their own, above all else she tries to make sure that they are able to live their lives as comfortably as possible with a place to call home.

The fragment of her memory in Elysian Realm still recites lines from her previous performances. Not much is said about Eden's past other than her stardom and fall from the spotlight. As a novice, she was very determined to reach the top. Apparently, she was really picky about venues and bookings, which made people think she had a huge ego. She cut ties with the company that managed her and secured a performance on her own. The first venue she got a spot on was a small one for charity. Some of the people who attended recorded her singing and posted it online, which garnered a lot of attention. Professionals praised her talent, and said she would rise to popularity at some point. There were also critics, of course. Despite the challenges on her path, Eden did rise to the highest stage. Her generosity and talent brought in more and more fans until she was the biggest name of her time. She lived in extravagant homes, and drank the finest wine, all while improving with each performance. But Honkai ended that life.

Kuchisake-onna (literally Mouth-Slitted Woman) is a recurring ghost of the Gakkou no Kaidan. The most common version of he story in Japan, is that she was a woman who decided to have a plastic surgery, but the surgery went wrong, leaving her mouth torn, ear to ear. She was originally going to was to be the ghost of the third episode of the Ghost Stories anime, but the episode was cancelled just days before it was scheduled to air, when many people complained to Fuji TV because they thought the facial feature looked like a cleft palette. A support group for people with such a disability met with management at Fuji TV. The episode was replaced for that airing with a hastily-prepared clip show. Only the preview remains. It is unknown what Kuchisake-onnas mouth was to look like in Ghost Stories, viewers only get a pink flash of it in the 15 second promo. She did appear in the ending credits but due to the low quality its hard to tell what her mouth really looks like. It appears that she might have fangs or crooked or sharp teeth and that her mouth extends all the was from her lips to her ears. In the 1995 movie however her slit mouth resembles that more of the mouth of Kuchisake-onna depicted in the 2012 movie Kuchisake-onna Returns where her mouth and lips are fully torn off and she has extra rows of sharp and crooked teeth.

Nothing shows this quite as much as her behavior around the protagonist. The man who was the "Weakling" commanding her old comrade's "third-rate squad" is now a "Junior Blockhead" whom she can (occasionally) rely on. Though she maintains the "tough" in "tough love."
