Ir regards to your question, I've been thinking of this: If Utsuho can control nuclear fusion freely, could she initiate endothermic fusion on transferric elements and use that to
Cool down the reactors
Create other useful elements for different uses such as suitable fuel for a fission reactor to be used in conjunction with the old hell's reactors for massive efficiency?

But you are forgetting that heavy metals take more energy to create than gained from the fusion. Hopefully that is a sunspot and not a ball of heavy metals, or it is going to destabilize exponentially as more metals are formed and density increases.
I'm curious of that too. We only use uranium and similar elements for fission since it produces the most efficient energy that we can manage. Fusion uses hydrogen since it's abundant in the sun and it produces the most energy. We didn't use other elements because of its low energy output or ridiculously high energy cost.
If Okuu can bypass that and just start the reaction, that means she can fuse and separate all the other elements, making her ability kinda like manipulation of matter.
Up until iron the fusion releases more energy than it takes. Seeing as Okuu can initiate exothermic fusion even without the prerequisite heat and pressure present, it wouldn't be unreasonable to assume she could do the same on iron and heavier. The suns she shoots as a result of the (presumably hydrogen) fusion radiate heat and light around them proving they're exothermic. Here are my hypotheses:
Okuu's power lets her ignore the energy requirements for initiating nuclear fusion or the required energy is provided from Yatagarasu's powers. This would suggest that she can fuse anything she damn well likes including transferric elements and have it produce energy.
Okuu can only fuse deuterium, or Hydrogen-2 and can't reach temperatures required for heavier fusions, namely Hydrogen-1. This would mean she doesn't shoot suns but brown dwarfs which is decidedly less cool although slightly funnier. (YMMV)
When a fusion reaction is initiated by Okuu, she "borrows" energy from nothingness and the difference is "paid back" during the reaction. For fusion of heavy elements this would mean energy is absorbed from the environment. This could work as a powerful coolant for something.
Hypotheses 1 and 3 mean she could, for instance, create fissile materials for a fission reactor. Then the nuclear waste from that could be used to fuel a fusion reactor for a nearly infinite loop. Hypothesis 3 even helps in the architecture as there's no need for big cooling towers or other cooling facilities. Of course there would be some loss of energy as nothing works with 100% efficiency, but it would be pretty darn efficient energy production anyway.
I really like the third one. She can use a literal "Cold Fusion", unlike our "Not so Hot Fusion". By the way, how's it going with that? Did that Andrea guy manage to convince everyone that his e-cat works? I can't seem to find any news after he supposedly did an exhibition last year.
Also, I've never been sure so I'd like to ask. Can we make other elements from mixing or separating lighter or heavier elements? Like, usual fusion reaction in the sun can turn 2H-1 into He, and that one beam that can change chemical composition of the thing it blasts. Anyone can give me an explanation/clarification?

If so, Okuu's ability can be really useful.
The way it works is that every atom is made of X-amount of protons, Y-amount of electrons, and Z-amount of neutrons. Fission rips them apart and that is what we do with reactors in operation. Hydrogen is a single neutron so it works well for Fusion where 2H atoms will compress and fuse to make a single He. With each Neutron the element changes. However if it is anything like lab results the iron you get this way would be radioactive.

Also, in atoms the number of protons is always equal to the number of electrons. Otherwise they're ions. Not that electrons are terribly important when talking about fusion reactions on a simple level like this.
Iron has three stable isotopes: Fe-56, Fe-57, and Fe-58. Fe-54 is observationally stable, or it hasn't been observed to undergo radioactive decay, but is theoretically calculated to do so. Iron-52 has a half-life of over eight hours, Iron-53 over 8 minutes, Iron-55 2.7 years, Iron-59 44 days, Iron 60 2.6 million years, and Fe-62 over a minute. There are pretty good chances of that being iron and not being horribly radioactive. (Relatively. Of course anything with a half-life of barely over a minute is pretty dangerous.)
The easiest known element for fusion is Hydrogen-2 or deuterium. It has one proton, one electron and one neutron as opposed to run-of-the-mill Hydrogen-1 or protium which has zero neutrons. Deuterium burning or fusion of a deuterium atom with a proton forming Helium-3. To be classified as a star, a body has to have the required temperature and pressure for Hydrogen burning or fusion of H-1. "Just" 13 Jupiter masses is enough for deuterium fusion, but hydrogen fusion requires ~75 Jupiter masses to occur naturally.
Single protons, deuterium and other light atoms and nucleons are the most practical to use for the fusion of even heavier elements. Obviously you can fuse different kinds of atoms together. Otherwise we wouldn't have any elements with atomic numbers that are not powers of 2.
That being a sunspot is potentially even more alarming that it being the iron core. Remember that sunspots are caused by the enormous, violently whirling magnetic field around the sun that causes the thing to burp gigantic bursts of hot plasma. Imagine being anywhere near that.
Oh shit... I forgot the catgirl rule! Orin? Are you okay?
