The Undead Demigod stationed in Almeria City, titled "Edge of Grief," is a Resentful Spirit Bloodline Demigod of Level 32.
Much like Banshees, Resentful Spirits belong to the Ghost System of the four great Undead Races. Compared to Banshees, which tend to "weaken" enemies, Resentful Spirits are better at granting themselves various unique survival buffs.
For example, Mind Blind Zone (not attracting hate), Nihility State (halving damage from the outside world), Anti-Space (moving unimpeded by obstacles), and so on, and of course, the most distinctive feature of the Ghost System: immunity to pure physical damage. Whether it is swords or bullets, hitting them would simply pass through.
If The Azure Longsword truly ended up in conflict with this demigod, it couldn't be said that there was no way to fight. First, summon Miel, this little cheater, and pick a few girls to cover with "Future State," and you could immediately create several demigods who have crossed the Level 20 threshold.
