[You think by keeping a lesser number of beasts, you're able to keep their loyalty strong?]
[I think you're wrong.]
[One beast, two beasts, ten beasts, fifteen beasts, even an army of beasts, who said numbers have anything to do with loyalty?]
[Loyalty is an understanding.]
"An understanding?"
[Isha, no matter what you do, will forever be loyal to you.]
[Sure, she might flip out sometimes like she did recently, but you heard her words after she cooled down.]
[She knew deep in her heart that you're the one good guy she can always rely on.]
[Why do you think she would stop believing that just because you fused with more beasts?]
The question left Ryuk completely speechless.
[You have already proven your heart, Ryuk, and you have done it more than enough times.]
[The bond you share with her isn't something a decision—such as trying to grow stronger and fusing with more beasts—would break.]
