Novel Dangan Ronpa/Zero

Yasuke Matsuda (松田 夜助 Matsuda Yasuke) is one of the main characters in the Dangan Ronpa/Zero novel series. His title is Ultimate Neurologist (超高校級の「神経学者」Chō Kōkō Kyū no "Shinkei Gakusha"). He is a Neurologist whom was giving treatment to Ryouko Otonashi through the events of Zero due to her tendency to forget things caused by amnesia, who in turn is infatuated with him, and he seems to be the only person that she can remember more easily than anything else, Matsuda was also asked by Jin Kirigiri to 'extract information' out of the despair incident survivor Soushun Murasame.

Matsuda was eventually stabbed in the chest and bled to death by Ryouko, whom was in a fit of despair.

He is referred to as a 'sharp-tongued brainiac' by Monokuma's memo in his profile.


Matsuda has a tall, slender figure with a pale-like complexion. He has a small rounded thin-face, and he has messy black shoulder-length hair, he also has grass-green colored eyes. his attire consists of the Hope's Peak Academy uniform, however he does not wear the jacket or lab coat unless it is during his work as a Neurologist, however, mostly in his free-time he only wears a white half-tucked in top-unbuttoned white dress-shirt, which uncovers most of his upper chest along with a sloppily red-decaled black tie with bathroom slippers. 

His tall and slim appearance almost makes him a tad alike to Byakuya Togami. whom in turn, is also slender and tall. 


Matsuda is quite mean, rude and has a sharp-tongue, especially towards Ryouko Otonashi but also shows some concern towards her on account of her forgetfulness. It is shown that Matsuda can be quite evasive towards certain things, he often insults Otonashi for her clingy attitude towards him and frequently calls her a 'dung-beetle' and a 'dullard'.

It is shown he can bearly tolerate Otonashi, however at times he hints a sort of affection as reciprocations towards her feelings for him. although during so, before she is able to notice this. he brushes it off and becomes obscure with his words. This also concludes when Otonashi worries about not having to see him again, and him responding with a mumble "Don't worry, I'll never let this treatment end." 

He is shown to also be serious, and unfond of jokes often, being protective of Otonashi especially when the jokes are regarded towards her. This is seen when he is met with Jin Kirigiri and the rest of the committee, during then one of the old men of the committee had described Otonashi as a 'dunce with no hope of recovery' and reckons that she is 'too much of a failure'. causing Matsuda to respond angrily and contemptly by telling him to 'Shut the fuck up' and also calling him an 'old man', declaring "I am the only one who’s allowed to make fun of her. No one else has any right to." 

During the meeting, he is shown to be able to demonstrate dominance and intimidation towards other individuals, most definitely if they were to insult Otonashi.


He seems to have known Junko Enoshima ever since they were kids, this also concludes that she was already under the Alter Ego and guise of Ryouko Otonashi. and his mother died after having some kind of memory loss, even being made to believe he was just 'some kid she didn't know'. After her death, he tries to point out that he was free now that she's gone, but is obviously upset by it anyways.

Also in elementary school, Enoshima had been working on a sand church in the sandpit at the park based on the Sagrada Familia for an entire month, only for it to be destroyed by an unknown culprit, causing her to break down in tears for almost a whole day. Matsuda in result had gotten angry, and decided to search for the perpetrator.

Matsuda's investigation wound up in a dead end, and had never found any witnesses and ended up becoming depressed during the time, one day he was sitting on a bench infront of the remains of the sand sculpture quietly, until Enoshima ran up to him with a large smile and whispered in his ear to keep it a secret, telling him that she was the one who destroyed the sculpture all along.

Matsuda asked why, and Enoshima responded by saying it was an accident.

After some point in time, he had enrolled into Hope's Peak Academy and reunited with Enoshima while she was still was still in her alternate identity. 


  • "That girl... Even when people make fun of her, she swipes it off because she thinks it has ‘nothing to do with her’. That’s why I have to speak up for her. I won’t be able to live with myself if I don’t."
  • "Shut up already, will you?"
  • "Shut the fuck up, old man. Your dirty mouth talks too much."
  • "This is probably my chance. My chance to protect her."

(to Ryouko Otonashi )

  • "You’re also too loud for someone as ugly as you. Speaking of, someone as ugly as you being scared of flying scalpels is weird too." 
  • "You sound like a stalker."
  • "...Honestly, your brain is like a bottomless bucket."
  • "Who are you going to report me to? The National Japanese Ugly People Association? That kind of organization would be guilty of discrimination just by existing."
  • "I really can't leave you alone for a second, can I..."
  •  "…You don’t often see someone possessing such a superb, brain-intensive talent as you do affected by memory loss. That’s why you’re such a rare case."
  • "...I'm sorry."
  • "Still, in the future you should talk to an expert about it. But, if you can’t do that, come to me… That’s all there is to it, right?"

(to Jin Kirigiri )

  • "Clarify the truth...? Isn't that a contradiction? Didn't you decide to cover up the incident?"
  • "…So who is this student you want me to interrogate?"
