Reincarnated as a Goblin: From the Start, I Carried Off an Elf Priest

[Villain protagonist, mildly dark, reincarnated in another world] Glain is reincarnated as a low-level monster, a goblin, and an adventurer party arrives as expected to slay him. Glain takes an unconventional approach, killing the superior goblin shaman instead and carrying off the party's elven priest. Thus begins his legendary life. Many years later, the world's various factions are sharply divided in their opinion of him. Archbishop of the Holy Church: “This goblin is the most evil creature I have ever seen. I cannot allow him to profane holy magic. We must slay him!” A certain king: “Right, he must be slain!” The Elven Queen: “I won't tolerate the Church and humanity slandering Sir Glain like this. He is my beloved, and also my daughter's…” A certain Demon King: “Glain is my dearest friend, my brother from different parents! Are you sure you want to do this?” A certain hero: “I… am no match for him.” … The wheels of time roll on, and everything seems predestined. Witness how this little goblin lives out a brilliant goblin life!
