Shinitagari no Shannon: Dragon ni Taberaretemita Shannon Wants to Die! Eaten by a Dragon

Synopsis

Shannon is a totally normal, mortal mage, and certainly not older than she looks—at least, that's what she's convinced her new friend, Kyle, into thinking. Cursed to live forever and fed up with her immortal coil, Shannon wants to...well...die! Unfortunately, nothing has worked—not poisonous mushrooms, not falling from cliffs, and certainly not old age. But that doesn't mean Shannon has given up. If there's a will (and perhaps a dreadful dragon, a toxic tincture, or some deadly dungeon traps), there's a way, and Shannon is committed to her search for the sweet release of death.
