Ren Maaka (真紅 煉, Maaka Ren), the oldest of the Maaka children, has no qualms about sucking blood, and believes vampires to be superior to humans. He prefers female victims, seducing them and often spending days in their company before he's done with them, and refuses to suck on male blood. He states that sex was only used to keep him under control during the day to prevent Brigitte Braunlich from escaping. He has accidentally impregnated Bridget when he used sex as a mean to control her during the arc when Karin is kidnapped. He was informed of the conception over the phone and it shocked completely both him and his family. Though he abandoned his former lover, he expresses no interested in having a relationship with her and is shown to be indifferent towards both Bridget and her son Rei. In fact, he still doesn't even want to think about either one.
Ren sees the act of biting as a metaphor for sexual intercourse, and often commits both acts simultaneously. Ren often appears annoyed at Karin for her seeming lack of vampiric abilities and her friendliness towards humans. While he will listen to his mother Calera Marker, Anju Maaka is often the one who will calm him when he's annoyed or subtly prod him into acting in certain ways. He greatly fears Elda Marker, whose overly affectionate manner when he was a child causes him to flee at the mere sight of her.
Ren shows an extreme distaste for humans, seeing them merely as an energy source. He has stated that he will only feed on women and considers feeding on men disgusting. Though most of this may be due to a Self Denial of being gay as in high school, where he bit a boy named Makoto Fujitani, thinking he was a crossdresser. This humiliation and sense of betrayal could be the source of his hatred. In the manga, his first bitten human was a female teacher at the school instead. He seems to still have feelings for Makoto as you can see he looks shocked to see Makoto with girls, jealous even. In the manga, he attends middle school where Makoto is portrayed by a girl named Hinata Fujitani.
Ren would meet his son years later when also meeting his niece Kanon. Attempting to protect her and return her to Kenta when she wandered off into the woods. Though Kenta offered to have him come and reunite with his sister, he quickly refused. He stated that if she saw him, her memories would return. He does get to meet his son. Though its not known if he voluntarily came to meet Rei. Or if technically Bridget caught him and forced him to stay. He was completely frozen when Bridget introduced them. Not responding to Bridget’s claims he’s come to be with her, romantically. Or to be a family. Judging by his shocked state, he most likely doesn’t want to be with Bridget or be a father.
- Ren seems to care for both of his younger sisters
- As seen in Volume 10, Ren is the only one out of the 3 siblings to have met his grandfather James.
