Kozo Ichinose

**Kozo Ichinose** (一ノ瀬 耕三, *Ichinose Kōzō*?) is one of the main characters in Taizan 5's manga series, The Ichinose Family's Deadly Sins.

## Etymology

* His family name **Ichinose** means "*one*" (一) (**ichi**), (ノ) (**no**) and "*rapids/current*" (瀬) (**se**).

## Appearance

Kozo is a man who has lived a long and full life, and his physical appearance reflects this. He is short in stature, with white hair that speaks to his age. His face is lined with wrinkles, which are a natural result of the passing years. While he may not be one to smile often, this does not mean that he is unapproachable or unfriendly - in fact, Kozo has a calm demeanor that can be quite reassuring to those around him.

During his introduction in the series, Kozo is wearing a hospital gown. This is because he and his supposed to be family were recently involved in an accident while on their way to Fukui for a mini family vacation. The entire Ichinose Family was affected by the accident, lost their memories, and they all had to wear hospital gowns as they received medical attention.

## Room

    Kozo's room is a sight to behold, with mathematical and scientific equations covering every inch of wall space. It's clear that he has a passion for these subjects, as evidenced by the sheer amount of papers and chalkboards dedicated to them. In fact, Kozo claims that he was once a professor of physics before the accident that landed him in the hospital, apparently. This explains why his room is such a mess of equations - it's clear that he has spent countless hours studying and researching topics related to their unending incident.

Despite the chaos of his surroundings, there is an order to Kozo's madness. Each equation seems to have its place on the walls or chalkboards, forming a complex web of knowledge that only someone with his level of expertise could understand fully. It's clear that Kozo takes great pride in his work and accomplishments as an academic..

While some may find his cluttered room overwhelming or confusing, it serves as a testament to Kozo's dedication and intelligence. He may be physically limited due to his injuries from the accident, but mentally he remains sharp as ever thanks to his love for mathematics and science, as he was able to provide information related to the incident, which that includes that they're already about to get their 2000th incident loop.

## Background

In addition to his impressive academic background, apparently, Kozo possesses a unique ability to remember and analyze the events of the 2000 loop accident that he and his supposed to be family experienced. He claims that he was able to take detailed notes on their situation during each loop, allowing him to gain a deeper understanding of what was happening.

Through his calculations, Kozo discovered some fascinating insights into the nature of the time loops. For example, he determined that Tsubasa was only able to remember certain events from previous loops twice before forgetting them entirely. This suggests that there are limits to how much one can retain from each iteration of the loop.

Kozo also analyzed Kakeru's decision-making process throughout the loops and probably discovered something - which made a different choice in one particular loop, Kakeru was able to completely change the course of events and erase himself from their family tree.

## Relationships

### Tsubasa Ichinose

Tsubasa is Kozo's grandson, apparently, and while they haven't had many significant interactions, Kozo has shared some information with Tsubasa about his notes on the 2000 loop accident.

### Shiori Ichinose

Shiori is supposedly the granddaughter of Kozo.

### Sachie Ichinose

Sachie, Tsubasa and Shiori's supposedly grandmother, is Kozo's wife, apparently.

### Minako Ichinose

Minako is Kozo's daughter-in-law, she is supposed to be the mother of Tsubasa and Shiori.

### Kakeru Ichinose

Minako stated that Kakeru is still living in his parent house-the house they currently living in. In chapter 31, there is a family picture of Kozo, Sachie, and Kakeru. He is Kozo's biological son, apparently.

## Trivia

* He claimed that before the accident, he had been a professor of physics.
