IIRC, that wasn't Hayashi - that was the original Metroid creator who did the story.
Which is exactly what he wants you to believe.
The guy who wrote the story for the original NES ninja gaiden games was also on staff for NG3, which had an atrocious story. Writing up a script and implementing it are two entirely different things. That heavy handed story telling was 100% Hayashi, even if he did not conceive the original script he is absolutely responsible for how it was handled within the game.
If he came out today and said "hey, i had nothing to do with the story in NG3, it was the guy who did the NES ninja gaiden's" he would be telling the same lie he told with Other M.
People don't really care that the story is bad. Most stories in gaming are bad.
We care that its bad, and in your face, and it won't shut the fuck up and let you play the goddamned game because it's too busy being a story.
Look at the second level of ninja gaiden, the airship stage. it starts with a cool cutscene that hypes you up for the boss battle at the end of the stage. It's only purpose is to give you exposition and look fucking raw while doing it. You spend the entire level doing ninja shit and killing people, and then you get to the boss and kick his ass. Then you get a cool fucking cutscene of ninja shit going down and explosions happening as a result. That's all there was, cool shit at the start, cool shit at the end, and solid gameplay in the middle.
Now look at the second level of NG3. Few minute long cutscene with a character you care nothing about, and an over explanation of the introduction of your bow weapon. about 20 or 30 seconds of killing later, ayane shows up for another minute or cutscene and the explanation of a replacement sword.
You finally move on but the game keeps shoving its fucking radio chatter bullshit down your throat like its metal gear solid. Get ambushed by an enemy? Doesn't matter that it was obvious, the game will be there to tell you about it. Clear an area? Yup. Gota wall run like a ninja? Radio time for that too. New enemy type pop up? You better believe she's gonna talk about that.
In fact, if you actually die 3 times in one area, you'll actually get a metal gear solid style "snaaaaaaaake!" game over screen, complete with the radio bitch yelling your name, along with the games attempt at insulting your intelligence by asking if you'd like a lower difficulty. Unlike ninja dog in NGB, they will never stop asking you this question.
Get to the end of the level, and there is another lengthy cutscene, followed by a boss fight. or, I'd like to call it a boss fight, but it's honestly just three or four minutes of some QTE bullshit. Then more cutscene, then the level ends, then more cutscene, then the level starts with more QTE, then some mindless hack'n'slash in a dynasty warriors fashion, then more cutscene, and more radio, and so on.
The entire game is like this.
Funny thing is, they could have told the EXACT SAME STORY and kept the overdramatic bullshit out of the game. People would not have complained nearly as much. But that's not Hayashi's style, he wants to be like a fucking movie director or something and cram as much storytelling in as he can. He needs to go work for Hideo Kojima, not Team Ninja.
