Sentimental Komuro Michael Sakamoto Dada-sensei (センチメンタル小室マイケル坂本ダダ先生, or simply Masada, or Seccom Masada-sensei) is a character that inhabits the Spaceship.

Overview

Seccom Masada-sensei is a monochromatic humanoid character. They appear to wear a solid black suit or jumpsuit, alongside having black, medium-length hair and a pale face with strabismic, gray eyes. When interacted with, he makes a trilling, robotic noise, which is also used for one of the Neon Creatures.

He is found in the Spaceship, of which he appears to be the pilot. He is initially facing a large organ at the front of the ship, though he will slowly turn to look in all four directions randomly. If the Spaceship Crash event is activated, he will be frantically looking in all four directions, as if he is panicking, and will make a higher-pitched noise when interacted with. When the ship finally crashes on Mars, he will instead make a lower-pitched noise when interacted with, possibly signifying that he is upset by the ordeal.

If the Knife effect is equipped near him, he will slowly back away continuously.

In the manga

Masada as he appears in the manga.

Seccom-Masada sensei is one of the main characters of the Yume Nikki manga. He is first seen after Madotsuki stabs her pen through her dream diary, which causes ink to flow out onto the desk and onto the floor, forming a pitch-black puddle that Masada emerges from. In order to enter the dream world, Masada must also sleep in a bed just like Madotsuki. It is also revealed that, in the dream world, Masada is a sort of puppetmaster that hides the world's effects, helping the watchful Mars-san who serves as his boss.

After being alerted of Madotsuki's increasingly violent tendencies, Masada goes to the Nexus and finds it in ruin. He summons his organ which he plays to summon a Paracas figure, which points him the way to Madotsuki. He eventually confronts her on Witch's Island and is nearly stabbed, though he isolated Madotsuki by cutting the island's dock in two with his own knife. However, he is suddenly stabbed by an umbrella, which is revealed to be the doing of Poniko (as Uboa).

During the story's climax, Poniko beheads Masada to limit his control and takes him to Mars-san. Poniko is tasked by Mars-san to stop Madotsuki's violent rampage, with Masada's head simply being turned into a window design on Poniko's shirt so that she can carry the effects, similar to the design Madotsuki has. Upon finding Madotsuki in her bed, Masada urges Poniko to kill her, though Poniko instead attacks the dream diary with the Knife effect in order to free herself and Madotsuki from the dream world. This upsets Masada, who realizes the dream world will begin to collapse as a large creature made of Madotsukis' bad memories forms in the Nexus. Poniko is consumed by the monster, leaving Masada's head and the effects in Madotsuki's Room. Masada realizes he can use the dropped effects, flopping his disembodied head onto the Stoplight effect to regain his legs and kick the effects into the monster's mouth. This causes Madotsuki's memories to flood back, causing the monster to explode as the effects are dropped into the Nexus and Masada tumbles back into Madotsuki's room. Madotsuki awakens, frightened by seeing Masada's head in her room. Masada reassures her that she is still dreaming and tells her to go onto the room's veranda so that she can "wake up for real".

Name

As for most characters of Yume Nikki, the name of the character was created by fans. "Sekomu/Seccom Masada-sensei" (セコムマサダ先生) is a shortened mash-up of his full given name, "Sentimental Komuro Michael Sakamoto Dada-sensei", which is a combination of various names:

• Se = Sentimental, which appears to reference the tone of the game
• Ko = Komuro, after Komuro Tetsuya, a Japanese pianist and songwriter.
• Ma = Maikeru, the Katakana of "Michael" from Michael Jackson, an American songwriter and singer.
• Sa = Sakamoto, after Sakamoto Ryuuichi, a Japanese pianist.
• Da = Dada, after an alien race from the Ultraman series that share a similar appearance.

Additionally, "Seccom" is a result of an English-language simplification of "Sekomu."

Trivia

• Masada is one of only two characters who can walk backwards in the game (the other one being Dave Spector). He does this 'moonwalk' when the Knife effect is equipped. This is the origin of the "Michael Jackson" part of his name, due to his imitation of the iconic dance move, and the similarity in appearance that Masada shares with the entertainer.
• The honorific suffix -sensei attached to his name is to imply that he is an authority figure, as many fans imagine him as a music teacher, due to the fact that Madotsuki is allowed to play the organ in his Spaceship as well.
