Character from Mob Psycho 100. Founder and owner of the Spirits & Such Consultation Office, and Sachi's boyfriend (later husband). A socially and emotionally intelligent man (usually) that has few qualms with manipulating others (clients, enemies, and even allies) to his own advantage. While he doesn't use his fast-talking nature for anything particularly nefarious (other than lying about being a psychic...running a business that deals in psychic-related jobs), it definitely isn't wrong to think he's a shady character running a shady business. That said, he is a (mostly) honorable and caring man that believes hurting others is wrong and should be avoided whenever possible.

Sachi sees right through his ruse the first time they meet, and is more than happy to give him a good ribbing about it. Having someone around his own age that sees him for exactly what and who he is that still opts to stick around and even want to hang out with him takes time for him to learn to accept, since he, deep down, doesn't currently consider his existence in other people's lives as a positive.

Character from Yu Yu Hakusho. Wielder of the Dragon of the Darkness Flame, master swordsman, Riyo's lover, and father of Kaen and Sachi. A demon that prefers to keep his distance from others with a cynical view of others (especially humans). Is a bit of an arrogant turd and quick to squabble with some of his teammates (particularly Kazuma Kuwabara). Despite that, he does stick to a personal honor code and under all his emotional constipation, he does care about his comrades.

Meets Riyo after Team Urameshi gets through their first round. Originally thinks she's just another bothersome human, which he is very correct about. However, he underestimates just how annoying she can be to a point where she's managed to worm her way under his skin and eventually cements herself a special spot in his heart in essentially no time. He grows a similar respect for Riyo's tenacity and skills as he has for Yusuke and Kurama (and begrudgingly, Kuwabara).

Riyo and Hiei's only son and second child (is thirteen years younger than Sachi). While he really enjoys learning new techniques and abilities to use his energy on (particularly since it means getting to spend quality time with either of his parents and sister), Kaen is very unlike the rest of his family and isn't all that interested in fighting (taking part or watching). Having been raised in the human world all his life (unlike his older sister, whom spent a chunk of her own childhood in demon world), he just wants to lead a regular and peaceful life (as close as he can get as someone that's only 1 quarter human, anyway).

Is a lot like his mother in that he's quick to want to make friends with just about anyone he meets.

Granddaughter of the world renown psychic Genkai, Hiei's lover, and mother to Sachi and Kaen. Is a powerful psychic in her own right (though finds out later on that that is due to being half-demon); she specializes in healing and defensive barriers. An easy-going gal with a love for family and friends, as well as watching a good fight. When she sets her mind to something, damn near nothing can stop her from her goal (which is anything from freeing the demon world from King Enma's control, to bugging the guy she likes into coming out of his shell).

Went to university to become a teacher, which she goes on to do when she, Sachi and Hiei make the move back to human world.

Current Spirit Detective of the human world, Riyo and Hiei's first child and only daughter, and Arataka's girlfriend (later wife). A bright and outgoing woman with a love of fighting same as her parents and master (Yusuke Urameshi). Greatly enjoys her work as Spirit Detective, but finds it isolating due to needing to drop everything to deal with trouble, which has led to not being able to keep a hold of platonic and romantic relationships throughout her 20s.

Once she decides to stick around Seasoning City, she ends up working on a freelance basis for Arataka's business.
