Segen National High School

**Segen National High School** (背現 (せげん) 国立高校 (くりつこうこう) , *Segen Kokuritsukōtō*β) is one of the background settings of the *PHOBOS* series. It is a private high school located in the Kyoto of Kalina, which many members of the main cast attend, including Mora, Ran Luyus, Levyll Bloodsyl, Tae Tetsukimi, Ehuang, Mami Tōnoharu, Baiko Kishimoto, Chiasa Arata, Minazuki, Hanako, Nana, Yuriko, etc.

## Information

Segen National High School is a high school school with a high bar for entry. While still participating in events like the cultural festival, it is much more focused on serious education than other schools, leading to Minazuki and Chiasa's low grades. However, it does have plenty of interesting club activities to decompress after their difficult, rough education. Those club activities are also supported by trophies and national competitions. Segen is noted to have a seventy-three year history, though another educational institution stood in its place before. Due to its age, it has many rumors or ghost stories, such as a set of "seven school wonders" and else.

## Uniform

Segen National High School has a distinctive and recognizable set of uniforms. Male students wear usual white dress shirts (short-sleeved or long-sleeved) with black pants, white shoes, and a tie.

The female uniform has a similarly usual design, although some can make it unusual. It consists of a serafuku-styled long-sleeved shirt and a pleated skirt alongside brown shoes. For example, Minazuki's consists of a blue pleated skirt with a white serafuku-styled shirt and black shoes. Meanwhile, Mami's consists of a black pleated skirt and a white serafuku-styled shirt accompanied with brown shoes and a yellow ribbon.

## Seven School Wonders

The **Seven Wonders** (七不思議 (ななふしぎ) , *Nana Fushigi*) are a common set of rumors present in schools. Because of Segen High's relatively long lifetime, there are many rumors about the school, and has its own set of Seven Wonders.

### The Yūrei

**The Yūrei** is a young woman with incredibly pale skin and long, stringy black hair that appears near the second floor's classrooms and roams the hallways for something. Unironically, the punchline is that this "yūrei" is actually a confused Yoku Yokuchi looking for Ehuang's hiding spot after school, where she would usually smoke or skip.

### Baiko's Desk

**Baiko's Desk** is a strange rumor, or rather, one of the Seven Wonders of Segen High. As described by its name, it's Baiko's desk, quite literally. For some reason, if someone stares at the desk after classes for approximately two minutes, the apparition of an unknown girl can be seen sitting on Baiko's desk.

### Greens Beneath

The "**Greens Beneath**" is one of the Seven Wonders of Segen High. It implies a strange, green glow down in the sewer systems or ventilations after midnight hits.

### Residence of Snakes

The Residence of Snakes is said to be home of a snake lady, though it was proven false.

### Rintag

The **Rintag** is one of the Seven Wonders of Segen High. It is in this list due to somehow being able to transport one to another dimension by *walking through a **wall***.

### Eight-Foot-Tall "Baddie"

The "**Eight-Foot-Tall 'Baddie**'", as it generally screams, is the actual Hachishakusama. She was said to stalk the students and kidnap them, although she mostly doesn't move or appear there before it gets fairly late, with the first ever to see her being Mora walking home, much to his annoyance, which eventually led to him naming her the "Eight-Foot-Tall Baddie".

### Fourth Floor's Clockwork

The **Fourth Floor's Clockwork** is one of the Seven Wonders of Segen High due to being a strange malfunction in the fourth floor's clocks, which was said to show time as "24:61" after it hit 12 a.m. instead of going to 1 a.m.
