I reread it twice and both of you were good, however, i had to choose a winner.
And the winner iiiiisss:
Positive Aspects (TheTailedSage):
- Convinced me that most of Danzo's Fuuton are able to match Hiruzen's Katon, if not overpower him.
- Proved that Danzo even with his sealing braces on his a capable opponent.
Downsides (TheTailedSage):
- Used wrong scans about Danzo's speed (he used Izanagi at least in the first scan as he was shown to be smashed).
- The seal in his arm was shown to take some time to release, but your persisted with the idea that they don't and even used Izanagi in your argument when he wouldn't be able to use it.
Positive aspects (Thundercles):
- Proved well that Hiruzen's taijutsu will give him superiority in CQC and maybe give him the victory.
- Mentioned the shadow clones, which can also overwhelm, help defending or even assist the real Hiruzen in overpowering Danzo.
Downsides (Thundercles):
- Made use of non canon material (Gifs. There was no taijutsu before Enma being summoned).
- Used some fanfiction Lol (attributing jutsus to Hiruzen, even Genjutsu).
Thundercles, i don't think you were really the underdog like Zexion said because the restrictions made this match up fair and at the same time unfair. The restrictions should have included Danzo starting without his sealing brace because indeed he needed Fu and Torune to act as a diversion in order to have time, they require prep.
Having said this, Danzo couldn't have access to Izanagi and TheTailedSage, that involved part of your argument, but i think Thundercles did very well and for me he won.
Both were good nonetheless =D
