Arataka Reigen
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.
