So I was able to find a translation on YouTube:
Raiden was born with a condition where his muscles grow abnormally faster making his bones, who could not handle the muscles, break everytime he tried to walk as a kid. So the solution he came up with he somehow developed a new kind of muscle (like a shell) to contain the rampant muscles. So he was able to become the strongest sumo wrestler without ever going at full strength. However, with this volund he's able to go full strength without any negative setbacks and finally show his true strength. Now back to the garden with Loki and Buddha, Loki wonders how even with divine weapons, humans and their mortal bodies can withstand the full strength of the gods and asks him more questions. He then mentions a technique/teaching in Buddhism whereby putting two souls in the same boat/path, one can pull their true strength. Buddha asks "Loki what's your point? " To where Loki responds with, "are you a traitor?" Buddha answers by saying "what if I am?" Loki replies with "I'll kill you." Out of nowhere, Bishamonten and his 7 lucky gods (aka heavenly executioners) show up to execute Budda because they overheard the word traitor. Also out of nowhere, Sasaki, Kendou, Okita show up sensing a battle and join Buddha.
Full creds to Joe Matsuzawa on YouTube for that lol.
