Summoner to Dekiteiru

Amon is a half-breed summoner whose demonic tattoos glow with every spell she casts, and whose footsteps are accompanied by whispers from the underworld. She joins the squad of paladin Roni, the embodiment of order, restraint, and monastic discipline. Everyone considers them opposites, capable only of driving each other mad. But on the very first day of their joint raid on the cursed altar, something goes wrong: the ritual spirals out of control, blood and magic mix, and the fear of death pulls them together in a single, fiery touch. At dawn, they emerge from the ruins wearing masks of calm — but now every glance hides a flash of secret flame, and at the edge of the world, where the laws of the gods end, their own dangerous game of "man and demon” begins.
