My thoughts about the combination of Gojo and Utahime
To get started with this, you need to note some information as follows: Time/ Utahime's CT range/ Technical reduction of the sorcerer
Scene 1: Utahime is introduced to her technique 単独禁区: Solo Forbidden Area is a temporary curse output magnification for any sorcerer within her range including herself.
Normally, a sorcerer's efficiency is 100% and for them, mastering the CT is mastering the reductions such as chant, hand sign, etc. will evaluate their skills. But Utahime doesn't ignore anything.
She uses chant, hand sign, dance, music and the efficiency is achieved by 120% by sublimating the CT as a ritual. Meaning Utahime had sublimated her CT to 120% due to her not skipping any steps.
But note, here her 120% performance is not for charging Gojo, it's for her CT. (as to produce higher output).
Scene 2: Then comes Gojo's scene, he combines with Utahime and performs chant, his hand seal along with Utahime. The fact that he reduced the step was considered perfect during his student time (meaning the output did not decrease when activated, is 100%).
So whether he performs chant or hand seal doesn't increase his effectiveness. But when done with Utahime, no step is missed. He also achieved an output efficiency of 120%. Note not to add together. It is highly effective for creating 200% Hollow Purple.
The combination of Gojo and Utahime does not stop there. Next I will talk about TIME.
The next execution of Hollow Purple, he must maintain time for it. In terms of time mentioned. Utahime also needs time to perform her CT by people having to buy her time so they can receive the charge.
There is no limit to the range of Utahime's CT, but with time and chant. Gojo can still perform the combination ritual ( receive charge from Utahime). Because the output amplification of the curse output is temporary and may require time to recover. It would be appropriate for the range of Utahime's CT to be wider.
起こり: refers to the cause, the origin when an event begins In the scene before chanting for Red. This cursed energy is called “Origin”. It is the source of Gojo's increased energy output.
This previously assessed through domain expansion has hit the target, due to the great technical activation coming from “Origin”. The domain expansion had hit the previous target due to Gojo's curse energy being greater than usual.
After talking about “Origin”, Gojo is also the one who is a highly effective person of the curse energy. Speaking of "Origin" and Gojo makes the hollow purple even stronger. The curse energy that “Origin” was Utahime. Her CT charged to Gojo through chanting, maintaining time.
That helps increase the output energy (Red, Blue, Purple) but at the time will be limited in time and must buy time to recover.
Domain expansion timing indicates maintaining a state of increased output for the sorcerer. At the same time, it also calculates the time for Utahime's next recharge because it is temporary and requires recovery time for Hollow Purple.
I think normally when Utahime uses her CT, she doesn't do it herself as a ritual but needs time to recharge others. Performing the ritual with all the steps was intended to increase the effectiveness of her CT. Gojo then combines with her to both increase by 120% and create 200%. This amount is also reasonable as it says regarding the binding vow to produce 120% output. If you want to count the buffs, she buffed him 80%.
巫女舞: Miko-Mai. It refers to the miko's ceremonial dance. She performs the ceremony accompanied by Gagaku (雅楽), a type of elegant, classical court music using traditional instruments such as the biwa. she performed Kagura.
