Devin Westbrook/Summons

As a user of Ethereal Body Subordination Magic, Devin has several — in not hundreds of spirits under his command, all through the use of his signature weapon; due to him having a unique keenness towards the afterlife after the tragic events of his events, he's able to deal with the strain of utilizing various spirits at a time — especially for a young man of his age. Each one of his spirits are known to be extremely powerful in their own right, belonging to various races — some of which are known to be phantasmal in nature. It's unknown how he's able to conquer them all, but he notes that some of them came to him, feeling a strong attachment to the world they lived in before their passing; they see him as a way to continue living on before deciding when they feel the need to cross over to the other side. He also notes that he's able to collect spirits through the use of his Praesepe Magic, one that also deals in the manipulation of souls; however, he only uses this method when he deems necessary, opting for the first method — seeing it as more... mundane.

It's noted that out of all the spirits in his collection, there are ten that he uses mainly for combat purposes — used as somewhat of a last resort, as their skills are enough to decimate any opponent they go up against; it's because of them that many see Devin as unbeatable by normal means. Each one is incredibly powerful in their own right, taking much effort to defeat them. Due to their shared theme of black, they're dubbed as the "Dark Necrospirits" (, Dāku Nekurosupiritto; lit. "Demonic Warlords of Utter Annihilation Stained Black"), by Devin himself — thinking that the name is accurate; he's noted to cherish each one of them greatly, taking "proper care" of them in his own way. They're the only spirits that Devin hasn't collected personally, already being part of the blade.
