Background / History

Nangong Natsuki joins the Special Class as one of two new teachers assigned to accompany its students into another world. She serves as the lead instructor, while Yor acts as her deputy; Natsuki is specifically responsible for teaching magic and handling the group’s overall safety and logistics. 82

During the class’s first transfer, Natsuki uses a purple Space Magic array to teleport everyone to a Dungeon entrance. She later places emergency-return marks on the students, allowing them to teleport back to safety if necessary. 83

After observing Li Yu’s exceptional response to teleportation and his ability to comprehend spatial arrays, Natsuki tests his aptitude by personally teaching him Space Magic. She becomes his primary mentor in the field and continues providing increasingly advanced spatial techniques as his strength grows. 84 129 212 213

While operating in Orario, Natsuki helps manage the Hestia Familia’s expansion. She and Yor secure Haruhime’s release from the Ishtar Familia, arrange for transferred residents to receive housing and identification in their new world, and oversee the relocation of allies from Orario. 125 149 151

As Boundary University’s Special Class develops, Natsuki reorganizes the students into five-person teams, sets progression requirements for interworld missions, and warns them that they must become stronger if they wish to keep pace with Li Yu. 173 229 232

Natsuki also becomes responsible for receiving and integrating people rescued or recruited from other worlds. She adopts Kayo Senju, takes Sakura in as a spatially gifted apprentice, helps settle elves arriving from another world, and provides a home for Sakura and Xia Shi. 205 226 238 247

Appearance

Natsuki is a petite woman associated with Gothic Lolita fashion. She is first seen carrying a small parasol and later outfits Sakura and Xia Shi in matching Gothic-style clothing. 82 83 247 248

Personality

Natsuki maintains a serious, authoritative demeanor in front of students and takes her responsibilities as an instructor seriously. She gives direct orders, establishes clear strength requirements, and treats interworld travel as a matter requiring preparation and discipline. 82 151 173 232

She is highly practical in negotiations and security matters. When securing Haruhime’s release, she relies on Yor’s strength to ensure the Ishtar Familia cannot resist; when a Dimensional Rift appears, she immediately alerts security forces, evacuates civilians, and begins assessing the threat. 125 212

Despite her strictness, Natsuki actively nurtures gifted students and vulnerable children. She takes special interest in Li Yu’s spatial aptitude, adopts Kayo Senju, accepts Sakura as an apprentice, and works to provide children brought from other worlds with safety, education, and a stable home. 83 205 237 238 248

She is notably irritated when others append “-chan” to her name, particularly Yor and Li Yu. 108 198
