Kaido has dark pink hair, which is spiked back, matching color eyes, and sharp features.
Kaido wears a black jogging outfit, with stripes of blue lining the jacket's collar and arms, and black shoes. Kaido has a feral look to him.
Personality
Kaido, at first, seems to be a good guy that doesn't like to see other people make senseless riots. Ironically, he starts displaying his hot blooded self once he starts getting obsessed with power throughout the game. At the end of most routes, Kaido shows his brutality and total disgust to people weaker than him. He is especially protective for Mari, for whom he harbors a deep crush that he doesn't like to bring up to others (though he feels a bit embarrassed that Mari was his older brother's crush, and that he is younger than both of them).
Profile
Devil Survivor
Note:Significant plot details follow.
The leader of the charismatic "Shibuya Daemons", 20 years old, known as "Kaido". In contrast to his appearance, he has a reputation of being very helpful.
Originally, his older brother was the Daemons' leader, but he was the first victim in what is now known as the "bloodless murders." Shortly after taking over the Daemons, he came across a COMP and swore revenge upon the criminal. This desire, coupled with the loss of a "demon-hunting" bet he made with Yuzu, calls forth Pazuzu, demon king of the wind. Depending on the player's choices, he can either kill Keisuke in retaliation for the latter's murder of Daemons or aid his childhood friend and crush, Mari Mochizuki, in her battle against his brother's killer.
During the lockdown, Kaido teams up with Honda most of the time when fighting demons.
Early Bad Ending
Kaido does not show up at all.
Desperate Escape
He assists the party in making a distraction on the SDF barricades to allow them to escape the lockdown.
In Overclocked, Honda appears shortly after the protagonist and the others have dealt with the angels, referring to them as 'comrades', similar to the original ending when he called the three heroes for creating a world dictated by power. He expresses both grief and hate over the loss of his son, and through out the whole storyline, he searches for a demon that is capable of bringing his son back to life.
When the party arrives at the top of the Hills Building to confront Kuzuryu and Belberith, Honda laughs at how Kuzuryu was willing to throw away Belberith's power since his goal was accompkished, and states that if the Shomonkai didn't want it, he would take it. Belberith, seeing his desire to find a strong demon to revive his son, accepts his offer, and shortly afterward, the battle begins.
As soon as Honda's HP has been depleted, Belberith offers Honda assistance with the help of the demon Bephomat, which will continue to restore Honda's HP and MP until either Belberith's HP has been reduced down to the red zone or Bephomat has been defeated. If Bephomat has been killed, then after Honda's defeat, Belberith says that Honda will be able to see his late wife and son again, only to devour Honda. If Belberith's HP has been reduced before defeating Bephomat, then Belberith will devour Honda, restoring what HP he lost, and with his reason for being here gone, Bephomat leaves.

Devil Survivor Overclocked
Man's Decision
The party find Kaido being persecuted by SDF soldiers, his COMP having run out of battery power. If rescued, he will join the party.
The King's Decision
Kaido generally encourages the Overlord to kill anyone that gets in their way, angel or demon tamer. He will grudgingly agree to hold back if the protagonist decides to not harm humans. If the player agrees with killing humans though, he will tell Mari to leave the group in order to spare from being involved in their dirty work.
Hero Vs. God
Kaido is seen defending a barricade from a horde of demon tamers trying to get out at all costs. The party assists him and the SDF in stopping the big wave, but he does not join the team, cheering from the sidelines after seeing their good actions paying off, while he defends the barricades from being taken down.
Stats
Kaido is a physical-oriented fighter, boasting incredible Strength and Vitality values that exceed Atsuro's. However, his horrible Magic stats leaves him vulnerable to damage from magic skills, and his low agility and speed of 47 often leaves him the last to move.
Here, Kaido and Honda challenge the protagonist's party to see who can defeat more demons in the area. Kaido even comes with a Basilisk and Nalagiri in his team to make defeating the demons much easier for him.
If the player fails to keep Kaido from hunting Keisuke down, they will have to fight and defeat Kaido after he kills Keisuke. If the player does give Mari's bag to Kaido, he instead appears during the fight with Kudlak with the same stats.
