Raidou at the end of any boss battle. He flourishes his sword, then sheaths it as he turns his back to his enemy and completely ignores it while it explodes into green energy. This crazy shit is all in a day's work for Raidou Kuzunoha.
The final battle against Abaddon-Shinado itself, which has Raidou literally cutting his way through the embodiment of despair, jumping on top of it to dismantle its defenses and taking it down once and for all,showing Shinado that underestimating humanity was not the smartest move to make.
Even more awesome when you realize that during the final phase of the final boss battle, the game's Main Theme plays throughout!
Also,the Heroic SacrificeGeirin Kuzunoha pulls of near the end of the game and the subsequent resolution by his protege count as well.
Raidou and Taotie teaming up to use Taotie's "space-eating" power to pull the Abysmal Gate and the Pojitrawn together.
