Masaomi Dewa

is a member of HOMRA.

Appearance
Masaomi is a slim, young man with short, black hair and dark eyes. In addition, he wears squared glasses and a derby hat. Around his hat is a dark ribbon that outlines the brim.

His attire usually consists of a white undershirt, black shirt and a light-colored jacket, buttons closed, over both. He wears light-colored pants underneath and additionally dark-colored shoes.

Personality
Masaomi is calm, composed and serious. He is more rational than some of his Clansmen and is also one of the quieter individuals. Nonetheless, he remains friendly with them, especially with his constant companion, Yō Chitose.

Masaomi's loyalty is tied with his relationship with the members of HOMRA; in the midst of danger, he would willingly step forward to protect them. At times, however, when caught in others' shenanigans that would be potentially life-threatening to him, Masaomi occasionally jokes that they receive the same amount of injury as him.

History
Masaomi met and befriended Yō Chitose sometime in their younger years, eventually developing an "inseparable relation".

Late in February, everyone in HOMRA decided to go out and play baseball. When it was time for Chitose to bat, Masaomi hastily brought him forth. Chitose batted and nearly hit a woman with the baseball. Not long after, she attacked Chitose, as she was already looking for him before, causing the latter to flee. Masaomi and Totsuka chased after him and eventually pulled him in an alley.

Not long after, Totsuka received a phone call from Izumo. He handed it over to Chitose who, after an awkward but brief conversation with the Red King, was explained more about the woman chasing after him: Maria Yubikiri. While they're is talking, Masaomi concludes what actually happened between Chitose and Maria. He declares that Chitose did not stand a chance. Once Chitose was done talking to Izumo, Masaomi also stated that Maria was likely to kill them.

The three are then confronted by Maria who attacked them; luckily, Masaomi was able to pull both of his Clansmen from harm. They soon fled and split into groups, as per Masaomi's own suggestion for Totsuka's sake.

Chitose and Masaomi headed to the same bar where the former met Maria. While there, Masaomi scolded his friend for deliberately bringing along a woman he'd dumped for life, causing Chitose to explain he wasn't. While Masaomi was talking, Chitose suddenly began to recall his experiences with Maria and reached out for his friend's chin; thus, mimicking the same gesture he'd done to Maria before. Masaomi's unease began to surface.

Maria eventually arrived at the bar and began to destroy it. Masaomi briefly blocked Chitose though he stepped out, suddenly embracing Maria, and apologized for not fulfilling their promise before; things quickly became much more at peace. Soon after, Masaomi and Chitose returned to HOMRA, where their friends greeted them.

A few months later, Kōsuke and Anna brought a horse with them to the bar, where it was eventually revealed that it was also a Strain. Masaomi noted on how bad it was to even have the horse and scolded Kōsuke for it. He added that he should not go along picking up strange things, clearly referring to Eric in the context. A while after, as Izumo is cleaning up the bar again, Masaomi began to play around with his Clansmen. It wasn't long until they were all informed by Izumo that the horse Strain fled from Kōsuke, Kamamoto and Eric with Anna still riding on its back. Masaomi immediately darted out from the building to go search for her.

During the month of September, Totsuka decided to attempt skateboarding. Everyone in HOMRA was there to watch him unsuccessfully attempt some of Yata's trick moves, laughing all the while. Although, when Totsuka began to sing a song for Anna, Masaomi and the others immediately quieted themselves to enjoy the music.

A year and a half later, Masaomi joins his Clansmen as they watch old footage recorded by Totsuka. Once they are all done watching the videos, he joins the others as they leave to complete a new mission.

Plot
Masaomi, Chitose, Bandō and Shōhei head out to a warehouse near the city's harbor. They go inside and rummage through the crates, where they discover dozens of mechanical weapons. It is then that they all realize they've found the missing gun dealer's spot, such a person being the provider of the pistol used to kill Totsuka. Masaomi wonders how Izumo could have known so much about the gun dealer's warehouse and is hit on the head by Bandō for questioning him. Soon after, the four are approached by ex-member Saruhiko Fushimi, who easily knocks them all unconscious.
