i would suggest doing a "trial" run and bimbofying her the normal way, copying all the text from the scenes into a text file and then dive into the files.
in kiro's case, the code is probably in the main or content_follower .js files (wouldn't know since chars like kiro show up in multiple js bundles because fen and his circus of retards love to make spaghetti their out of their code), then just ctrl+f and look up for matches in the code with the help of your giant copypasta file. try looking up for short bits of non-variable sentences like npc speech for best results.

this is an example of me looking up the anno huskaring flags. highlighted in green is the text i looked up for and in yellow is the flag. keep in mind that the location in that bit of code could be either at the top or bottom (due to lack of coding consistency from the devs) and that flags may have multiple values that could mean multiple stages of transformation and etc. also if you want to delete/reset a flag you should set them to "null" instead of 0.
another thing to keep in mind is that certain characters (like anno in this case) also have changes done to their in-game object through certain function calls like in this bit

in this case the function _o is executed right after the scene where anno get's huskarred (you can see where function is called in the previous picture right near the bottom of the scene code, exactly above the "processTime(30)" line). in tits js they decided to obfuscate most scene function names, unlike in coc2 where most scene functions are left as they were originally in the source, so digging through the code is even more annoying in tits than it is in coc2. either way, this all means that you can't just simply change the flag and call the function to make all the npc transformations happen, instead you gotta change the flag and then painstakingly change every variable in the npc's object that is called in that specific function.
with all that said, while this isn't necessarily hard for me and many others that have dabbled in coding and such, for someone who's just beginning this is a lot to take in and learn just for making a rather simple change in their save, which is why most folks rely on third party save editors instead of doing things manually like this. so, if you're desperate enough to get into this then all i can do is to wish you good luck and to have fun.
