Why stop at exile?
1. Identify the tyrant.
2. Form a conspiracy and stab the tyrant 23 times.
3. Save the roman republicturkish stratocracy from tyranny.
Personally I feel that if it's executed well and/or looks nice I don't see why can't the artist reuse panels/scenes.
Also, reusing scenes is nothing compared to what Kyoani did for endless eight(15 years ago).
If I recall so far the assistants are all of a lower rank than the executed and knowing Ieyasu this was probably personal instead of political. Also has Oribe been denied his death poem?
