Love your obsession with Little Miss Bliss.
Besides Omega v. Naito and the ones that Rainmaka! mentioned, I also enjoyed these matches from Naito:
Katsuyori Shibata v. Tetsuya Naito - G1 Climax 26 - Day 8
Tetsuya Naito v. EVIL - G1 Climax 26 - Day 14
Definitely not on the level of Omega/Naito as far as match quality but it's worth the watch.
And, what a detailed article, Rainmaka! I loved it. Tetsuya Naito's transformation is one of my favorite Heel turns of all time, along with The New Day. His character as a disrespectful, egotistical Heel makes it that much better, especially since it's done in Japan. The way he carries the IWGP IC Title and throws it on the floor clearly proves that.
Not to mention that he's the leader of one the hottest Heel stables in NJPW right now ever since Devitt/Styles became leader of BC. His story is a miracle honestly and WWE should take notes to possibly test it with their Samoan "golden boy."
And yes, I believe Tetsuya Naito is a much better Heel than Minoru Suzuki, The Miz, Charlotte, etc.
An article for Kenny Omega and his journey (leader of the Bullet Club, G1 Climax, six-star match, etc.) to the IWGP Heavyweight Title would be cool to read!
