Sentinel of the Realm

Also known as [Beautiful Agent Companion Is Actually a Berserker] [You ask me why my Touch of Permanent Freeze travels faster than light? Can I not fire bullets faster?] [Having trouble casting the forbidden spell? Come and get this rocket launcher When the tide of monsters in the abyss was torn apart by my heavy machine gun, I thought this was all about crossing. Until I discovered that the original owner of this body was being "erased" by the chip, and this life contract itself was a death notice. The ace agent Lenisa, who was also being hunted, and I were forced onto a dead end - we fell into the monster's lair. As a result, the dragon in the magical world collided head-on with my rocket launcher; the forbidden spell of the elves watched her sniper rifle's "over-the-horizon strike". What's even better is that my time traveler's soul happens to be the perfect container for practicing the most powerful forbidden magic; her iron will is enough to control the most violent physical enhancement techniques. We originally wanted to keep a low profile, but the "organization" that took advantage of the abyss followed closely. Their blue crystal weapons originated from the plunder of this magical world. Therefore, in the machinations of the Elf Council and the Human Kingdom, on the ancient battlefield against the abyss, the muzzles and staffs of the two "visitors from another world" quietly changed the balance of the war. We are not trying to conquer, we are just trying to find our own way to survive in this troubled world where two worlds meet. (The plot is a bit slow, but the pace picks up after Chapter 10. The current chapter read rate is as high as 80%. Please give newcomers a chance!)
