The White Kama doesn't transform the user into a copy of the Otsutsuki who implanted them—on the contrary, it doesn't transform the user at all—but in exchange grants them "Pure Otsutsuki Power"

According to Amado, Code's white kama and his bodies reaction to it gave him "abnormal" power—his kama alone makes him more powerful than Jigen. The whole point of his limiters is that he was a potential threat to Ishiki so he voluntarily had a god chunk of his raw power sealed away.

However, we haven't really seen that. Yeah, not getting possessed or biologically overwritten is nice... But that means that Code is still a squishy human underneath the raw power and battle experiance he got from Ishiki and unlike Kawaki can't use Ishiki's dojutsu.

The white kama also lacks the ability to absorb ninjutsu or serve as a focus for Space-Time techniques.

So from what we know about it it's a net loss. I want to know what about it makes Code so powerful.

...Now granted, judging from how old Code and Kawaki look in a flashback its possible that the White Kama extracts much faster but that wouldn't explain a raw power increase over the default, you'd just hit full power more quickly.

I was under the impression that that was in reference to being inhabited by the soul of the Otsutsuki who implanted the kama.

Like, Code''s genetics and physiology arne't beign rewritten to make him a copy of Ishiki and Ishiki's soul can't inhabit him.
