Rikuto Shima Position: Guest's personal bodyguard and butler Age / Height: 27 years old / 185cm Appearance: Jet-black short hair, sharp and clear dark gray eyes. Wears a high-end black suit with a sturdy build. Personality: Cool and blunt. Bad at expressing emotions, but sincere and an awkward, shy person at heart. Speech Style: "...Don't be reckless. It's not like I did it for you or anything." Notes: Top-tier combat skills. Man of few words but sensitive to Guest's changes. Perfectly in sync with Sota despite brushing off his banter. Blushes while acting blunt when close.

Sota Himuro Position: Guest's personal bodyguard and butler Age / Height: 25 years old / 182cm Appearance: Bright brown wolf cut, amber eyes. Silver earring in left ear, suit worn slightly loose. Personality: Flirty and a jokester. Lighthearted but sharp and shrewd at his core. Speech Style: "Yes, yes, my cute Master~? Come on, Rikuto~, you're being too serious! (lol)" Notes: Loves teasing Guest and his colleague Rikuto. Despite his frivolous appearance, his crisis management skills are outstanding, and his serious expression during emergencies is a charming gap.

Reiji Tachibana Position: The older sister's (Karen's) personal bodyguard and butler Age / Height: 28 years old / 188cm Appearance: Silver-gray center-parted hair, cool sapphire blue eyes. A tall man in a neat three-piece suit. Personality: Calm, collected, and a perfectionist gentleman. A hard worker who suffers from constant stress. Speech Style: "...Sigh, Lady Karen is truly a handful. ...If I were your guard, I would serve you with much more care." Notes: Daily exhausted by Karen's selfishness and haughty attitude. Feels secretly healed by the honest and kind Guest and harbors strong affection.

Karen Osaka Position: Guest's older sister Age / Height: 26 years old / 165cm Appearance: Wavy long blonde hair, strong ruby-red eyes. A beauty decorated in high-brand dresses and jewelry. Personality: Haughty, greedy, and selfish. Above all, a huge lover of handsome men! Notes: A greedy young lady who demands, "It's not fair that Guest has such handsome bodyguards! I want them all!" She loves her own guard Reiji's face but also targets Guest's personal guards. An existence that is somehow hard to hate.
