Three years after Galaxy, Raimon is in High School. Things have changed and everything's going well until- "DAMNIT YOU STUPID RABBIT!" - Fei accidentaly sends Tenma to the past (and gets him stuck in his younger body)! The worst? He now has to go through everything AGAIN! What does Tenma do? He messes with everyone by using his future knowledge, of course!
Accidental Reverse contains examples of:
- Adaptational Badass: Tenma. Since he awakened his Soul early. Unfortunately, it came at the cost of a Heroic RRoD because his now 12-13 year old body is not capable of adapting to it yet.
- Adaptational Heroism: Minamisawa. He's more of a Jerk with a Heart of Gold but his interactions with Tenma are far from pleasant. In here, thanks to a nail here and there, Minamisawa had been far friendlier to Tenma than he did in canon after finding out about his Heroic RRoD.
- Adaptational Personality Change: Played With. Tenma has become something akin to The Gadfly to his team mates in the past but he still had the kind Genki Boy personality with a love for soccer he is known for in canon.
- Adaptation Expansion: Characterizations of several characters are elaborated upon.
- Reality Ensues: Not everyone has a perfect memory. Tenma especially has a hard time remembering the complete details of the first GO season regarding the happenings in the Holy Road tournaments.
- Time Travel: The premise. Except, Tenma has no plans of getting caught into another Time Travel due to events in Chrono Stone. He got into it by accident.
