Touta Matsuda

Touta Matsuda (松田 桃太, Matsuda Tōta) (romanized as "Tota Matsuda" in the Japanese manga) is a young member of the NPA, as well as the Kira investigation team.

Character
As described in How to Read 13, his policing skills are lacking in experience, hence he somewhat impedes the investigation process. His brash attitude can get him into tricky situations at times (like when he infiltrated Yotsuba and had to fake his death to get out), much to the irritation of his peers. Despite not having much experience in the NPA, Matsuda has proven to be useful or even crucial to the success of a mission, bringing down the mafia members who were holding the death note they were after. Showing great proficiency in his almost instant responsive reactions to tight situations, Matsuda has demonstrated skill in the field of infiltration both as Misa Amane's manager Taro Matsui, (松井 太郎 Matsui Tarō), and in the case of Yotsuba.

Remarkably, his television habit can be a resourceful asset to the investigation team-- though its importance is rather insignificant. Despite his child-like, naïve personality, Matsuda manages to stay through quite a few dangerous situations, committing to the NPA far into the future of the series. He is also totally devoted to Light's dad, who appears to have taken young Matsuda under his wing.

Films
In the films, Matsuda is played by Sota Aoyama. Matsuda's role and personality are more or less the same as they are in the manga and anime. When Light is cornered at the end of Death Note: The Last Name, Matsuda shoots light while he is trying to use a piece of the Death Note that he keeps hidden in his watch.

Conception
Obata described Matsuda as "hard to predict and thus hard to draw." Obata said that Matsuda's character concept consisted of an "average young detective" and that Matsuda's character had "nothing unique about his features and his actions weren't consistent, so I didn't like him. [laughs]" Obata added that he was a "Matsuda-type" person and therefore did not like seeing "my own inconsistency" in Matsuda. Obata described Matsuda as the sole character who "looks younger" during the Near and Mello arc.

Relationships
Light Yagami: Matsuda's relationship with Light Yagami is rather complex and less professional in comparison to the other Kira investigation team members (excluding Soichiro Yagami). At the start of the series Matsuda knew very little of Light and even though he had met both of the Yagami children in the past, he merely knew him as Chief Soichiro Yagami's son, however when Light joined the task force he grew close to him and somewhat saw him as a friend. His attitude around Light is playful when comes to issues involving women (Misa or Takada). Though he has sympathy towards Kira's followers and thinks Kira's had good intentions at heart but simply went about them the wrong way, hence he shows sympathy towards Kira's followers. His positive relationship with Light, however, seems all but forgotten at the end, when Matsuda shoots Light four times at the warehouse when Light didn't seem to care about his father's death.

Soichiro Yagami: He rather views Soichiro as some sort of a father figure or mentor and before Soichiro's death, Matsuda would frequently come to him for advice or consult his doubts. Matsuda was the task force member who showed the chief the most sympathy during his voluntary imprisonment. At the end of the series, Matsuda was especially enraged that Light Yagami would insult his own father after he died.

L Lawliet: Lawliet or L viewed Matsuda as a reckless dimwitted idiot who impeded the Kira investigation. However at times he noticed Matsuda's unique skills and appreciated his efforts and skills occasionally.

Kira Investigation Team: The rest of task force view him as a reckless, naive young detective lacking seriousness for his work (including L, the former leader of the task force). His personality is especially contrasting to that of Aizawa's; often resulting in humorous upsets where Aizawa will yell at him for 'not taking his job seriously', and Matsuda apologizing. Despite Aizawa's frequent criticism, Matsuda seems to look up to him as a superior and consider him a friend. However some such as Mogi have yet to make a comment on his actions and personality.

The term "Matsuda you idiot" became a popular phrase throughout the Death Note series. Members of the NPA task force, such as Aizawa have said this. L has said this phrase on numerous occasions. And even during Light Yagami's unmasking as Kira, Light still manage to say this phrase before his death.

Shinigami Eyes
Although Light's father, Soichiro Yagami, made the eye deal with Ryuk, that was not what Light had planned. In the manga, Light sends the notebook, knowing Matsuda would suggest that he make the deal, and lose half of his life span. Light was correct about this, and Matsuda did volunteer, though Soichiro insisted that he should make the eye deal instead.
