An earthquake, another world, and a tentacle monster in his basement claiming to be his wife are just the beginning of a chaotic new life for Nick.

Even if he doesn't, he's at least not alone, for better or for worse.

The Soaring Dragon Continent is a world of summons, you can only become strong if you become a summoner! Yue Yang, an average high school boy, was suddenly transported into this world. When he woke up, he was greeted with a lot of worried faces and found out that he had assumed another person’s identity. Turns out he’s the good-for-nothing third son of the Yue Family, who had just recently drowned himself because of a failed engagement. Unlike the third son of the Yue Family who was useless in summoning, Yue Yang succeeded in making a contract with a summoning grimoire on his first try, even when the other guy failed for the past fifteen years. Others would have a headache making contracts with beasts afterwards, but countless beasts tried to gain favour with Yue Yang instead, acting like a good kid before him.

Warning: This is a rewrite of my previous fanfic— Every Hole is a Goal.Current World: Avatar: The Last Airbender***Executed for escaping his owners, Nik met a relieving fate of beheading with the circumstances of his corpse unknown yet having an honorable end of his corpse is not his greatest concern for he is given a chance at life again. Of course, this meant Nik now worked for an organization that sent individuals like him throughout the omniverse for some reason unknown to him.As they say, if for the penny, in for the pounding.Nik: Wait... I'm not a prost... ehm, rental 'helper' anymore. Do I still charge?An adventure of a lifetime, they say. One that never ends.***Note:1) I don't own any original lore.2) This is the most standard 'collection' type harem novel you will ever see, so, if this is not your taste... well, give it a shot still and see if whether the other aspects of fanfic can cover them or not.3) All the characters I write smut about will be 18+. I will make sure to tweak the fanfic a bit in that way to make sure that the story itself adapts to these circumstances.4) If tags like an orgy and incestuous relationship are not your cup of tea, then... this may not be the 'one' fanfic for you.5) If men and women of sexual 'socialness' more commonly termed as floozy and even more degenerative terms most likely known to you all is not your cup of tea, then I apologize once again, this fanfic may not be the 'one.'6) There is no ntr, but there may be netori.
