Hiiro Amagi my Beloved

In Delicious in the Abyss, we follow various groups of adventurers as they explore the "abyss" a mysterious place filled with various fauna and monsters. No matter their race or age, most of them have the same goal: becoming the master of the abyss... However, some have a very different idea of how one should explore the abyss. Take for example a certain group led by an elf named Shen Yuan who desires one thing only... eat as many different monsters as possible!

Shen Yuan's party :

Shen Yuan: Elf, 87 y/o, Mage. His wish is to eat and study as many monsters as possible. He started exploring the abyss about twenty years ago, but had to stop abruptly after taking in Luo Binghe. On the surface, his studies seem to merely be for the sake of curiosity... But are they?

Luo Binghe: Tiefling, 63 y/o, Tank (and cook). Thrown into the abyss at the age of 38 (since tieflings are a long-lived race, it means he was about 14), he got stuck in the lowest levels for few years before Shen Yuan saved him. He regards him as his savior (and one true love) and would do anything for him... even if it means cooking the monsters (he hates it, he hates it so much).

Shang Qinghua: Gnome, 87 y/o, Healer. Shen Yuan's oldest friend and the author of many infamous books. He stopped writing them about twenty years ago though, after he started to explore the abyss with Shen Yuan. He seems to be looking for something in the abyss, or rather: someone.

Liu Qingge: Tallman, 26 y/o, Swordsman. One of Shen Yuan's friends. He used to be part of the Cang Qiong guild but left it after a disagreement with one of his colleagues. Now he works for Shen Yuan with his younger sister, Liu Mingyan. "Uh? My goal? Get stronger. Mh."

Liu Mingyan: Tallman, 24 y/o, Swordswoman. Liu Qingge's younger sister, she accompanies him on each of his missions. She got an offer to work with Cang Qion mountain once but refused it once she learned her brother had left the guild. She's quiet but efficient, however, Shang Qinghua suspects that she might stick around for other reasons...

Cang Qiong Guild:

Yue Qingyuan: Tallman, 48 y/o, Tank. The leader of Cang Qiong, he's a respected individual amongst adventurers. However, he seems leniant on the vices of his vice-leader: Shen Qingqiu.

Shen Qingqiu: Tallman, 40 y/o, Swordman. Vice-leader of Cang Qiong. He's the reason Cang Qiong is exclusively made of tallmen, as he has a strong distate for any other races, especially elves. The only exception to this rule is his adopted daughter: Ning Yingying, a dwarf. He's the one who abandoned Luo Binghe into the abyss after discovering his true nature.

Mu Qingfang: Tallman, 29 y/o, Healer. The group's medic.

Qi Qingqi: Tallman, 31 y/o, Swordswoman. She wanted to create a branch specifically for women in Cang Qiong Guild's but because of Shen Qingqiu's veto on recruiting other races she couldn't make it work.

Ming Fan: Tallman, 19 y/o, Mage. A cowardly young adventurer. He has a crush on Ning Yingying.

Ning Yingying: Dwarf, 51 y/o, Tank. Despite being older than him, she's Shen Qingqiu's adopted daughter whom he took in when she was merely 30 y/o. She likes her father a lot, however she can't forgive him for what he has done to Luo Binghe. (She'll leave Cang Qiong to join Shen Yuan's part at some point).

(Side note, Cang Qiong is still specialized in cultivation, hence why most of them look so young)

The Tieflings hideout:

Tieflings are a race that I made up for this AU specifically, inspired by D&D. They're inhabitant of the dungeon, tall and sturdy, with pointy ears akin to elves, horns of various shapes and tails. They can also use magic like elves, tallmen or gnomes, however their magic rely on its own set of rules.

Mobei-Jun: Tiefling, 92 y/o, King of the Northern tribe. Leader of one of the numerous tiefling tribes hidden in the abyss, he met Shang Qinghua twenty years ago in the abyss and has made him swear his loyalty to him since then. He has sensed change in the abyss since Luo Binghe's arrival, and decided to trust Shen Yuan's party to solve this issue... With the compensation of Shang Qinghua.

Sha Hualing: Half-ogre half-halfoot, 15 y/o, Princess of the Eastern tribe. Adopted daughter of the king of the eastern tribe, she's a bastard born from the forbidden union between an ogre and a half-foot and was abandoned into the abyss at birth. Of short stature, with a short life spawn, she makes up for it with her keen senses and her strength. She later on joins Shen Yuan's party.

The first Tieflings:

Tianlang-Jun: Tiefling, ??? y/o, Master of the Abyss. The master of the abyss, his powers are beyond anything imaginable. He claims to have eaten what has given him those powers and since then has known hunger beyond what any mortal could endure. He has once fell in love with a tallman woman by the name of Su Xiyan, but she has left the abyss years ago, and he doesn't know what her whereabouts are... The only thing he knows is that she's the only one capable of satisfying this hunger that eats him from the inside.

Zhuzhi-Lang: Beastman (snake), ??? y/o, Guardian of the abyss. Tasked by the Abyss' Master to protect its inhabitants, he'll kill anyone who gets in his ways indiscriminately at the exception of Shen Yuan, who saved him years ago when exploring the abyss for the first time. He only obeys the Abyss' Master orders, and because of that, has forced the Tieflings deeper and deeper into the abyss regardless of how they felt about it. As a chimera, he's more snake than the tiefling his soul has been mixed with.

Other groups:

Huan Hua's guild (the governor's guild): The one guild financed by the governor of the state in which the abyss is located. Its members are from various races. Despite the guild stating they're open to anyone, only those from a wealthy background can become a part of it.

Zhao Hua's guild: Specialized in magic. They have rounds to reanimate unlucky adventurers in the abyss.

Tian Yi's guild: Specialized in training new adventurers.

And that's it for now! What awaits them in the abyss? Many adventures and delicious cooking, that is, if Luo Binghe can handle it.
