Below is a list of characters in Chrome Shelled Regios, from the novel, the anime, and the various manga adaptations.
17th Platoon
Layfon Wolfstein Alseif
Weapon of choice: Sword, Broad sword, Guan Dao, Steel threads and Katana
The main protagonist of the series In the novel, he is described as having tea-colored hair and blue eyes. He was one of the twelve wielders of the Heaven's Blades and also held the title of Wolfstein at the age of ten.
He and Leerin were found by Derk Saiharden during their early childhood and taken to the orphanage in Glendan. Due to Derk's inability to earn enough money (because of his old age and the fact that he had retired from the battlefront), Layfon decided to earn money fighting in matches in order to provide for themselves and the other orphans. He began to participate in illegal underground matches to earn even more money for the orphanage. His high levels of strong kei and fast mastery of combat techniques earned him a place amongst the ranks of the elite Heaven's Blade wielders at the age of ten, having been given the title "Wolfstein". His Heaven's Blade was a powerful longsword made of white DITE. Eventually, Gahard Barehn challenged Layfon for his title, secretly blackmailing him to lose with the threat of exposing his participation in the underground matches. During their battle, Layfon cut off Barehn's arm, though he had actually been intending to kill him in order to keep his secret safe. As the match had been overseen by Queen Alsheyra, she ordered his immediate arrest and capture in response to his actions. His having taken part in underground matches was later exposed, and he was stripped of his title and exiled from Glendan as a result. He went to start his life anew in Zuellni, determined to put fighting and military arts behind him.
He entered the Academy City of Zuellni as a General Education student with a D-rank scholarship. On the day of the academy's opening ceremonies, however, he attracted attention by unintentionally showing off some of his martial arts skills. In the manga, he throws two Military Arts students to the ground as a reflex to being shoved; in the anime, he saves Meishin from being crushed under falling rubble as a result of two Military Arts students fighting. He was forced to join the Military Arts after Kalian Loss, head of the Student Council, blackmails him into joining as he knows about Layfon's past, and publicly upgrades his scholarship to rank A, which automatically waives his tuition fees. Incidentally, Kalian was already aware of Layfon's abilities from having seen him fighting a filth monster while on a transit bus to Glendan several years ago.
Layfon has extremely high combat capabilities, as can be inferred from his past as a Heaven's Blade wielder, and also has the innate ability to break down kei techniques and use them just by observation. He mastered all the Phyharden skills in a short period of time and learned the secret techniques of the Luskans that even Savaris was proud of, the Thousand Men Rush and Killer Roar (Houkeisatsu).
Due to his birthplace, Glendan, being heavily involved in fighting Filth Monsters, he and fighters there developed with a 'win or die' philosophy. One either fight and become stronger or die. Consequently, he deliberately holds back in battles at Zuellni in order to conceal his past with unsuccessful attempts. He said that for him, the entire field is too narrow for him later on to Nina, which made sense since most of the matured pollutant beasts are huge and takes lots of effort to take down.
Felli mentions that he has a large amount of kei when he was unconsciously asleep after knocked out by Nina. Some of his abilities include being able to move at high speed which can harm a normal person's body, he could catch up with the rest of the martial artists while he went to escort Feli since she couldn't travel at the speed of martial artists. All the while he states that he is not moving at a high speed due to Feli's body conditions. This also enable him to use a technique to create illusory clones due to speed. Layfon currently works at a machinery cleaning job with Nina in the evening, which has bad working condition and hours but generous pay. His goal is still to find a dream outside of fighting, a decision made as a result of being exiled from Glendan.
