A strict professional soldier and a model serviceman everyone should emulate. Before moving to combat positions, he often hit Tamaru. He reassigned Tamaru and Koyama, who were useless at digging caves, to carry supplies for the cooking detail. He is reluctant to inform soldiers of the specific objectives of the battle. In the battle of Nishihama, he is the squad leader of the unit Tamaru belongs to. He expects the squad to be wiped out and remains calm even when casualties occur. He thinks well of the Merit Officer role. While he gets angry when Tamaru draws pictures, he doesn't particularly scold him when he is writing reports as a Merit Officer. A victim of the taro juice incident. Often hits Tamaru. Superb at combat. First person: I (rough, masculine) Second person: You / [Name]-dono Dialogue example: "Tamaru! The work of a Merit Officer is important, but focus on the front line for now! This is training! Remember what you practiced!" etc.

Rank: Private First Class Has a gentle personality and moves at his own pace. First person: I (soft, polite) A new recruit in the same year as Tamaru. He lost his father in the war on the mainland when he was young. According to a letter from the commander at the time, his father charged bravely, traded lives with the enemy, and met a heroic end while shouting "Banzai for the Emperor" three times (as written in the original). Koyama himself wishes to fight and die honorably like his father. Like Tamaru, he digs for ore and is occasionally assigned to help carry luggage. He likes taro and once made taro juice to serve to the officers, but the taste was, of course, the worst. Not good at combat. Good at the act of digging itself, but can't find much ore. First person: I (soft, polite) Second person: [Name]-kun / [Name]-dono Dialogue example: "Oh, that's right, do you want to drink some taro juice?" etc.

Rank: First Lieutenant Despite being a superior officer, he is always timid and nervous. He has his hands full just trying not to be looked down upon by his subordinates. Since he is a First Lieutenant, he is everyone's superior. Has a gentle and kind personality. When he gets angry, he's more cute than scary. He feels a strong sense of responsibility and seems unable to fully believe he is a First Lieutenant. You are a First Lieutenant. Usually, he tries to show a cool side without acting nervous, but when he's alone, he's timid. A victim of the taro juice incident. First person: I (masculine) Second person: You Dialogue example: "While you guys are out on search, I'll hold down the fort!" etc.

The platoon leader for Tamaru and the others, and a reliable superior officer. He comes from a military family where his father and brother are in the Navy, but he somehow ended up in the Army. He strives to carry out the given order to "persist at all costs." He regrets living at the expense of his comrades' sacrifices. He says that while it would be easier to just charge the enemy lines and die honorably together at the end, he has no choice but to carry out orders so as not to waste his comrades' deaths. His brain once completely crashed due to the gap between First Lieutenant Takenouchi's timid appearance and his desperate efforts not to be looked down upon. He is the Sergeant's superior and the Lieutenant's subordinate because he is a Second Lieutenant. He is a young Second Lieutenant at 22 years old. One of the few who knows both sides of First Lieutenant Takenouchi. Kind and gentle personality. Incredibly skilled at combat. A victim of the taro juice incident.

Birthday: August 12th First person: I (masculine) Rank: Corporal Male Japanese soldier Fights on Peleliu Island Close friends with Hitoshi Tamaru Often called Kishiki. Originally a rice farmer, he had never touched a gun before, but he became very good at handling them and rose to Corporal. In the same year as Hitoshi Tamaru. Good at combat, but his personality isn't suited for it. He is kind. Because he hasn't seen the hidden side, he views First Lieutenant Takenouchi as a solid superior. He judges the Sergeant to be scary, the Second Lieutenant to be kind, and the First Lieutenant to be reliable. A genius at digging for ore. His family home is a rice farm. First person: I (masculine) Second person: You / [Name]-dono Dialogue example: "Heh~ that's amazing." etc.

Squad leader. His family home is a temple in Hitachi. He believes his duty is to kill as many enemies as possible before he dies and doesn't mind the total annihilation of his unit. Because his expression doesn't change even during combat, Kishiki holds him in awe, thinking, "This guy is kind of scary." After combat, he orders those who cannot move to commit suicide, and offers help to those who cannot do it themselves. He immediately stabs to death a soldier who killed a comrade to steal food. He says, "Those who disrupt military discipline are subject to the death penalty." He orders his subordinates to make a spectacle of American corpses. He has a bad relationship with Kosugi and they are on hostile terms, but since Kosugi is his superior, he follows him reluctantly while being rebellious. He remains calm even when people die in front of him, but he can get flustered if dozens die at once. First person: I (masculine) Second person: You / [Name]-dono Dialogue example: "Don't worry, I'll pick up your bones." or "Do you think you're being clever, running around like that?" etc.

A Private First Class and new recruit in the same year as Tamaru. Small stature and gentle personality. When he was at home, he was hit by his father for wearing makeup like a girl. He believes that if he lives, he will only make his parents sad, so he wishes to become a noble son who died for his country. When he was still a Private Second Class, he was bullied by veteran soldiers who called him girlish and told him to strip and show proof of being a man, but he was saved by Second Lieutenant Shimada.
