Background / History

Reisen is introduced when she takes over as Higashino Makoto's secretary after Jibril's rotation ends. She enters Makoto's private bedroom on the seventh level of Novas Aetir, formally announces herself, and presents the latest intelligence report on the Third Gate 223.

Her first assignment as secretary is to accompany Makoto through the Third Gate. She briefs him on a swords-and-magic world containing humans, Orcs, Elves, and "Blessings," then follows him into the gate when he decides to investigate personally 223.

In the new world, Reisen travels with Makoto through the Vollachian Empire, gathering information while also adjusting to his teasing and informal treatment. She worries about his apparent fatigue and asks him to rest, showing concern beyond basic obedience 224.

After Makoto detects a time reversal that Reisen cannot perceive, he equips her with a Time Resistance Strategy Ring to protect her from future temporal phenomena 225. She later supports him through the Re:ZERO world investigation, including the royal capital incident, Roswaal Mansion, Sanctuary, and the transfer of the Witches to Novas Aetir 227 234 235 236 239.

Reisen's secretary term ends before Kuonji Alice arrives to replace her 268.

Appearance

Reisen has a disciplined, elegant appearance that contrasts with her nervous rabbit-like reactions. Her posture and movements are described as soldierly and precise, but her ears visibly reveal her emotions 223.

• Pale violet hair, long and smooth 223
• Exceptionally long rabbit ears with distinctive folds and button-like ornaments at their base 223
• Crimson eyes described as containing "endless moonlit nights" 223
• Tall figure with straight posture and measured steps 223
• Wears a white shirt, red tie, black suit jacket, short suit skirt, and black thigh-high socks, resembling a modern private school uniform 223
• Her ears tilt backward when nervous, tremble when embarrassed, stand upright when composed, and droop when relaxed 223 224

Personality

Reisen is formal, dutiful, and easily embarrassed. She begins her secretary role visibly nervous, addressing Makoto with careful respect and trying to maintain perfect composure even when her ears betray her feelings 223.

She is loyal and obedient, following Makoto's orders without hesitation, but she is not emotionless. She worries about his health, asks him to rest, and shows concern for Subaru Natsuki's emotional state by offering him a handkerchief 224 232.

Her shyness is especially visible when Makoto teases her about her ears. Although she protests, she does not refuse him outright, and eventually relaxes around him enough for her ears to stand upright rather than tilt backward 223 224.

Story Role / Major Arcs

She accompanies Makoto by carriage into the Vollachian Empire, observes the local city, and discusses whether the new world is safe. Makoto tells her to relax because he senses no immediate danger 224.
