Renri appears mild and kind, with a soft, gentle expression that makes him approachable.

Behind that calm face, however, he has a surprisingly sharp tongue and a playful, impish streak.

He is fundamentally warm-hearted and considerate of others, often acting as emotional support for those close to him.

At the same time, his experiences have made him cautious and a little guarded, especially about what he reveals to others.

Renri loves to take photos and eagerly looks for chances to snap pictures, especially of his friends.

He tends to channel his affection and curiosity through his camera, using photography as both a hobby and a coping tool.

Renri was born into a renowned family of spirit mediums, expected from childhood to awaken powerful spiritual abilities.

However, he struggled to fully awaken those powers, and his “training” quickly turned into abusive, harsh rituals masked as discipline.

During his childhood, he was forced through all kinds of exorcist training, most of which bordered on torture rather than proper instruction.

The situation turned tragic when one of these training sessions led to the death of his younger brother, a loss that deeply traumatized Renri.

The grief and guilt from his brother’s death pushed him into a severe mental and emotional breakdown.

He spent his early years in an environment filled with fear, pressure, and loss, which left lasting scars on his psyche.

Eventually, his childhood friend Kukuru Kasubata reached out to him and offered him a way out.

Encouraged by Kukuru, Renri ran away to the city, leaving his oppressive home behind.

Life in the city with Kukuru gradually dulled the sharpness of his painful memories.

However, over time Renri realized he could no longer clearly remember his deceased brother’s face, and that realization horrified him.

Shaken by this fear of forgetting someone he believed he must never forget, he confided in Kukuru.

Kukuru responded by telling him, “Take a picture of me,” and urged Renri to photograph him with a camera app.

By taking that photo, Renri anchored the idea that memories can be preserved and protected through images.

This small act helped him overcome his fear and gave new emotional meaning to photography in his life.

Later, Renri returned to his hometown to attend the funeral of Kukuru’s mother, traveling back as his companion and support.

During this visit, Yoimaru Azaki, who had been scouting Renri for some time, once again encouraged him to enroll in Yaden Academy.

Influenced by Yoimaru’s persuasion and his renewed connection to his origins, Renri decided to join Yaden Academy.

There, he entered Class 1-Otsu and began a new chapter of his life, balancing his painful past with the future he wants to build.

“From the Window of the World”

Renri’s electric ability, “From the Window of the World,” allows him to create supernatural “windows” in space using photos taken with a spirit-receiving device.

By photographing a specific area, he can later manifest a window that connects to that exact location and angle.

At first glance, the ability looks like a defensive power, since the windows can act as barriers or observation points.

However, its true strength lies in spatial movement: Renri can use these windows for teleportation between different locations.

This teleportation has a wide range of applications in combat and emergencies.

He can use it for quick escapes, surprise repositioning, or pulling pre-prepared weapons and tools from remote storage spots.

Each new window, however, consumes spiritual power, so he cannot use the ability recklessly without draining himself.

Managing how many windows he creates and where he places them is a key part of his strategy.

Interestingly, Renri kept the teleportation aspect of his ability secret from the rest of Class 1-Otsu.

He did not reveal the movement function until the Class Otsu vs. Class Kou battle, where it became a crucial element.

When asked why he hid such an important detail from his teammates, Renri bluntly admitted, “Because I didn’t trust everyone.”

This answer reveals both his lingering distrust born from past trauma and his habit of holding his true capabilities close to the chest.

Kukuru Kasubata

Kukuru Kasubata is Renri’s childhood friend and one of the most important people in his life.

Their connection goes back to their families’ ties, as Renri’s lineage of powerful spirit mediums is linked to Kukuru’s background.

Kukuru was the one who effectively rescued Renri from his abusive upbringing by inviting him to run away to the city.

Through this, Kukuru became both a savior and a stabilizing presence, helping Renri rebuild his life.

When Renri was terrified of forgetting his brother’s face, it was Kukuru who suggested using photography as a mental anchor.

By telling Renri to “take a picture of me,” Kukuru helped him reframe his fear into something he could confront and manage.

Renri, in turn, often wants to photograph Kukuru at every opportunity, blending his hobby with his emotional attachment.

Their relationship is a mix of mutual reliance, quiet trust, and unspoken understanding, with Renri’s teasing and sharp tongue adding a playful edge.

Yoimaru Azaki

Yoimaru Azaki had been scouting Renri for Yaden Academy even before Renri formally returned home.

Recognizing Renri’s potential, Yoimaru encouraged him to enter Yaden Academy after meeting him again at Kukuru’s mother’s funeral.

This recommendation was one of the decisive factors in Renri’s enrollment in Yaden Academy.

Yoimaru’s involvement suggests that Renri’s abilities and background are valued assets in the academy’s environment.

Renri has a calm, gentle aura that makes people feel at ease around him.

Yet his comments can be unexpectedly cutting, giving him the charm of a “little devil” who mixes kindness with sly teasing.

He loves photography and almost compulsively looks for moments worth capturing, especially in daily school life.

Taking pictures is not just a hobby for him but also a way to frame reality, preserve memories, and ground himself emotionally.

Travel is another of his passions, fitting naturally with his interest in different places and perspectives.

This also pairs thematically with his spatial ability, as both travel and teleportation are forms of moving through the world and its “windows.”

Food-wise, Renri is a picky eater and has a particular hatred for shiitake mushrooms.

He also dislikes rooms with lattice windows, likely because they remind him of his oppressive childhood home and training environment.

Because of his past, Renri finds it hard to fully trust people, even those on his own side.

This explains why he initially concealed the full extent of his ability from his classmates, using secrets as a form of self-protection.

Despite his guarded nature, Renri is not cold; he genuinely cares for others and shows kindness in his own understated way.

His combination of warmth, hidden trauma, sharp wit, and unique ability makes him a complex and memorable presence at Yaden Academy.
