|First Lieutenant Tsurumi will scold me!
This article is outdated, poorly written or lacks important information. It should be reworked!
Appearance[edit | edit source]
Like his brother, Nikaidou Kouhei has a well accented face with a thin, pointed nose. He has completely black irises, and his hair is black and cut very short, with a straight hairline. He is seen wearing the uniform of his ward.
Nikaidou is missing both of his ears; one was ripped of by a bear and one was cut off by First Lieutenant Tsurumi. He would wear his cut off ear on a string around his neck, but later on Edogai made him a headpiece out of human skin which the ear was sown onto where it goes over his chin. The headpiece covers most of his head apart from his face, with holes on the sides where his ears used to be, and a pair of nipples at the top.
After having his his leg cut off by Hijikata, Nikaidou receives a prosthetic leg from Arisaka which also doubles as a firearm. Nikaidou later loses his right hand in a battle with Sugimoto, so Tsurumi asks Arisaka to make him a prosthetic one, which has a chopstick compartment in one of the fingers.
Personality[edit | edit source]
Nikaidou appears mentally unstable, as he often ignores orders and seems to enjoy inflicting pain on others, which was shared with his twin brother, Youhei. After the death of Youhei, Nikaidou became obsessed with getting revenge against Sugimoto, often disregarding anything else when he finds himself face-to-face with him. His mental health also apparently deteriorated even further, as he refers to his lost body parts (leg, ears, etc.) as Youhei's instead. When told that Sugimoto had "died", Nikaidou lost his motivation and became a shell of his former self, refusing to move from his bed or eating his food. He seems to have become addicted to morphine after his many severe injuries, as he would steal entire bottles of it and just the mere mention of it was enough to get his full attention when everything else had failed.
Background[edit | edit source]
In Meiji 38 (1905), Nikaidou took part in the Battle of Mukden during the Russo-Japanese War. When 2nd Lieutenant Tsurumi and Hajime Tsukishima were severely wounded, Nikaidou, along with several 7th Division members carried them to a frozen body of water to be carried away on sledges for treatment. They came upon Sugimoto with a dead body who offered to let them use the sledges with one of the Nikaidou twins asking if he was sure. They then brought the two injured soldiers away to have their wounds treated.
During a blizzard storm, the 7th Division took shelter in a wooden building. While Genjirou Tanigaki and Tsurumi were having a somber conversation, one of the brothers whispered something into the other brother's ear.
Plot[edit | edit source]
|Spoiler warning: Significant plot details about Chapter 70 onwards follow.|
|in the coal mining town of Yubari, Nikaidou is staking out a fresh grave along with Tsurumi and Sergeant Tsukishima in order to catch a grave robber. As Tsurumi and Tsukishima are talking about whether or not the grave robber will come, Nikaidou holds up Youhei's ear to Tsurumi's, saying that it looks just like his, and asks him to give him his left ear. Tsurumi humors him by saying that he could have it when he dies, just then Tsukishima spots a silhouetted man in front of the grave. Nikaidou steps on a branch, which the man hears and proceeds to flee. Tsurumi tells his subordinate to chase after him, with Tsukishima telling Nikaidou not to kill him. (70)
Sometime after the chase, Nikaidou and Tsukishima are seen inside a house next to the Edogai Taxidermy store, with Nikaidou scouting and Tsukishima maintaining a rifle. Nikaidou questions if the taxidermist really has the skin, to which Tsukishima tells him that he talked to a doctor about the mining incident and that he dug up the grave to find it empty. Getting impatient, Nikaidou also asks if it would be better to just kill Edogai and search his house but Tsukishima tells him if Tsurumi really planned to kill him, he'd have done so once he answered the door. (71)
While Tsurumi is occupied with Edogai, Nikaidou manages to slip inside the Edogai house without Tsukishima noticing, and holds Youhei's ear up to Edogai's mother's ear, saying that her ear won't work. He then drops the ear into her clothings and as Nikaidou is attempting to retrieve it, Edogai comes into the room and finds him and his mother in an awkward position. He is able to obtain his brother's ear and move away to allow Edogai to let go of his past and shoots his mother's corpse. Afterwards, Nikaidou is shown banging a human drum with human bones to commemorate Edogai's recruitment into the 7th division. Sometime during his visit in the Edogai store, Edogai gave him a headpiece with his ear sewn on it.
Nikaidou returns to Yubari along with several 7th Division soldiers in order to erase the evidence left behind by Edogai and throws a molotov cocktail into the Edogai store to burn it down as he whispers to his ear that they've got to erase everything.
As they burned the Edogai store, Nikaidou ordered his fellow soldiers not to kill Sugimoto as he wishes to deal with him himself. When Ogata appears on the second floor, shooting at them, Nikaidou and the other soldiers rushed to the walls of the store to hide from his attacks. However, Hijikata began firing at them, knocking his cap off, forcing them to move away from the store. Given an opportunity to enter the store, Nikaidou rushed inside only see Hijikata preparing to cut him down with his katana. He was able to react in time to tackle Hijikata and overpower him. When he heard Sugimoto shouting for Hijikata, he stopped and looked up to see him, with an eager grin on his face. He yelled out Sugimoto's name and began to move towards the other man but is stopped when Hijikata cut his right leg off. Predicting Hijikata's attack, Nikaidou rolled away to hide from Hijikata, who gave up on finding him soon afterwards. Once Sugimoto and Hijikata's group left the store, Nikaidou crawled out from the store and roared in anguish.
Nikaidou was eventually brought to a hospital in Otaru where his wounds were treated. He would often steal some morphine and had to be restrained by Tsukishima and a doctor so as not to overdose. Tsurumi then came into the room and scolded Nikaidou, which caused him to fall into a depression. Tsurumi and Tsukishima headed out to meet an acquaintance and came back just as Nikaidou tried to steal another bottle of morphine.
As Nikaidou and Tsukishima struggled over the bottle, Tsurumi called out to him and said that a guest has come to visit him. Suddenly, a strange man came in and Nikaidou and Tsukishima are confused until Tsurumi shooed him away and Narizou Arisaka came in to introduce himself. When he produced a prosthetic leg, Nikaidou showed disappointment until Arisaka revealed that it can be used as a shotgun weapon. Nikaidou is amazed by his new attachment while a doctor came in to tell them to be quiet. Tsurumi, Arisaka, Tsukishima, and the strange man congratulates Nikaidou on his new leg.
After the raid on Abashiri Prison, Nikaidou was brought to a nearby clinic on the outskirts of Abashiri to be treated for his wounds, including the loss of his right hand. Sometime afterwards, he was told by Tsurumi that Sugimoto had "died", unaware that Sugimoto was in fact still alive and currently on a mission with Tanigaki, Tsukishima, and Koito. With the objective of his vengeance gone, Nikaidou felt he no longer has a purpose in life and refused to move from his bed or eat his food.
Nikaidou was then visited by Tsurumi who had heard of his current state from Usami and tried to get him to eat his food by rewarding him with some morphine. They are then visited by Arisaka who had crafted a prosthetic hand for Nikaidou, which piqued Nikaidou's curiosity. However, after finding out that the hand's special trick turned out to be a chopstick holder, Nikaidou was not amused and returned back under his covers. As Nikaidou recuperated from his wounds, he listened to Tsurumi talk about Kiroranke's past and his involvement with the assassination of Emperor Alexander II of Russia.
Some time later, the 7th Division visits a hot spring in Noboribetsu and Nikaidou and Usami decides to relax in a waterfall bath, which Nikaidou says feels nice. They are approached by Warrant Officer Kikuta and he says that since both Nikaidou and Usami are here, Tsurumi must be wondering how he is doing. Kikuta proceeds to tell them a time about when Private First Class Ariko met a strange man wearing geta in the middle of the night, calling it an odd story. Usami immediately dismisses the story but Kikuta says that they should hear it directly from the main source as Ariko joins them. He explains that he heard the sound of geta but found that the tracks the strange man left behind were from straw boots. Ariko goes on to say that the strange man was wearing clothes that had odd patterns on them but he was unable to identify them. Fed up, Nikaidou says that since both Kikuta and Ariko have been relaxing in Noboribetsu since the war ended, their minds have gotten soft.
The soldiers finished their bath and got dressed, continuing the topic as Nikaidou questions why Ariko was at a hot spring so deep in the mountains in the first place. Ariko reveals that only the Ainu knew about the hot spring and Nikaidou is surprised to hear that Ariko is an Ainu. Usami wonders if the strange man may have also been an Ainu but Ariko replies that he did not recognize the patterns on his clothes. Kikuta says that he found the story intriguing but that he may have also been overthinking it, asking the anma massaging him what he thought about it. The anma responds that he does not know anything about it but that he will be sure to tell them if he sees a strange man wearing clothing with a strange Ainu pattern.
Nikaidou and Kikuta jumps back into the hot springs to play around and Nikaidou is surprised by Kikuta blowing water out of his mouth. Kikuta turns to Nikaidou and asks him about the tattoo designs on the Abashiri convicts but Nikaidou shakes his head, saying that he has never seen one. Some time later, as Usami is getting massaged by an anma, Nikaidou wonders if they should bring Kikuta and Ariko back with them to Abashiri. Usami says that they will not as Tsurumi is leaving Abashiri and that they will meet elsewhere. Nikaidou then asks about Inkarmat and Kano Ienaga but Usami says that they are none of their business before turning to the anma to complain about his massage techniques.
Some time later, Nikaidou and Usami heads to the Hell Valley to help Kikuta fight against three blind men with Nikaidou providing support as a sniper. Nikaidou misses hitting one, causing him to run away and Nikaidou shouts to the others that the blind man is heading towards the mountain. Once Nikaidou had gone down to the base of the valley, he examines one of the dead blind men and recognizes him as being the anma who massaged Usami.
Four days after the ordeal with the convict, Nikaidou and Usami decides to rest once more at Noboribetsu while Kikuta heads out to search for Ariko, who had disappeared with Usami believing that he had died. Nikaidou asks Usami if he had sent a telegram to Tsurumi, which Usami confirms. Usami notes that Ariko had died, his leg got injured, and they let the convict escape, so he begins to panic that Tsurumi will come to scold him again.
