Shougo Aoshima is the former Blue Keeper, remembered for his tough and rough attitude but tragic fate. Once a delinquent who committed crimes for money, he was saved and later recruited by the Red Keeper. His journey from a misunderstood youth to a hero is marked by struggles, tough choices, and an ultimate sacrifice in the fight against the monsters. One of his most unforgettable traits is that, despite being very rude and difficult, he still cared for others in his own way.
Shougo Aoshima usually wraps his face in bandages, which cover wounds he got in a fight with a monster. He has a strong, rough look that makes him stand out. He often looks unfriendly, which matches his tough personality.
Shougo Aoshima has a very bad mouth and rough attitude.
He does not speak much in public because he does not want to be misunderstood.
This was advice given to him by Komachi Aizome.
He gets angry easily and does not get along well even with most of his allies.
However, deep down he is not a bad person; he has a hidden soft side and cares for people in his own way.
For example, his hobby is saving money.
He even donated money to the orphanage where he grew up.
When he was young, Shougo Aoshima lived in an orphanage run by the first Blue Keeper, Rikuto Aoshima.
After leaving the orphanage, he got mixed up in crime and spent time as a delinquent.
He did not really hang out with others and was usually alone, often playing puzzle games on his phone just to pass time.
- His boss, Komachi Aizome, often gets frustrated with Shougo’s rude language and behavior.
- Shougo once tried to help his former caretaker Rikuto Aoshima by giving him money for the orphanage.
- He was saved and recruited by Sosei Akabane, the Red Keeper.
- Other team members, including Souma (who would later become Blue Keeper), sometimes had a hard time getting along with Shougo.
Shougo has a lot of fighting skills, and he can use special equipment called the Blue Dragon Leviathan, thanks to cartridges made by Blue Squad ranked members.
He faces monsters and other enemies bravely, sometimes even when the odds are against him.
Troubled Youth and the Beginning
As a teenager, Shougo Aoshima was involved in crime.
One day, a man named Kamiya convinced him and his friends to rob a money transport truck.
They did the crime, but were caught by Sosei Akabane, the Red Keeper.
Red Keeper defeated them and tried to encourage Shougo to change his ways.
After this, Shougo gave some money (from the crime) to Rikuto Aoshima for the orphanage.
The Monster’s Trap and Becoming Blue Keeper
Later, Shougo got arrested for the crime.
Kamiya returned and said he made an alibi for them.
But the alibi was part of a bigger crime—a murder committed by a company boss.
Realizing this, Shougo broke free and confronted Kamiya, who turned out to be Andelga, a monster boss with the form of a tiger mixed with a cat and an octopus.
Andelga hurt Shougo’s face.
Shougo woke up, wounded and tied up.
Red Keeper appeared and gave him a choice: keep being a bad guy and get punished, or fight for justice and get revenge on the monster.
Shougo chose justice and became the new Blue Keeper, after Rikuto Aoshima was badly injured.
He fought Andelga and won.
Team Trouble
Other squad members were not happy about Shougo becoming Blue Keeper.
Souma, who was supposed to get the job, left the group in protest, so Komachi Aizome became acting second-in-command instead.
Final Battle and Death
One day, Komachi Aizome was helping train the new recruits by pretending to be a monster.
Suddenly, Peltrola, a real monster, showed up.
Aizome started losing, but Shougo came to help him.
Shougo found that Ranmaru Koguma, a recruit, had been replaced by a Footsoldier XX (a monster in disguise).
He tried to make XX talk by torturing him, but Hibiki Sakurama (actually Footsoldier D, in disguise) stopped him.
Soon, XX and D (Hibiki’s real form) revealed themselves, and Tsukasa Shippō showed up as well.
When XX surrendered, Shougo took both Hibiki and Tsukasa to where Peltrola was hiding.
Before going, Hibiki Sakurama warned him, “A move from a blind spot you never notice might take your life away.”
The team fought Peltrola and seemed to win, but then Hibiki Sakurama (Footsoldier D) showed his real monster form and challenged Shougo to a one-on-one battle.
Shougo used Blue Dragon Leviathan with multiple special cartridges to try to beat D.
But just as Hibiki had warned, he was killed by a surprising attack—a stab from D’s transformed arm, after being distracted by Peltrola’s laser.
Even D himself was angry at this result, saying, “I can’t accept winning like this.”
Shougo’s last words were, “Justice, evil... I, who am half-hearted, lost to true evil. That’s all there is to it.”
- Shougo hardly talks in public so people won’t misunderstand him.

- He likes simple games on his phone.

"Justice, evil... I, who am half-hearted, lost to true evil. That's all there is to it."
