Some Weapons suggestion are Avalon from Type-Moon, Cross Tail from Akame Ga Kill and some spiritual weapons.

I think you can find some interesting characters in games like Honkai Impact and Genshin Impact

By how you are empathizing Mama Goat charm ability are you going to make her like Tiamat from FGO with her mother love?

I still don’t understand how you can let one have more than one grimoire. You must go to another Kingdom to have another type of cover like Hearts or Clover?

Give to Goat Mama some pure Qilin bloodline, diluite some of Xiao Bing ice power to her and make an artificial Soul Tool using the principle of Soul sword or other similar things you can find in other Wuxia Novels in order to let the weapon grown together with its user. Let her reach 100.000 years old and you let her change into human form: you can have now Ganyu ( from Genshin Impact ). One of the earlier spirit ring for her can be an Ice Lotus like the skill in the game.

Will the MC create a new Intent like the Pregnacy Gaze of Death Seeker Song Shuhang? Death is nothing for experienced people let then feel motherly love by experience the hardship of pregnancy.

The common people speculate that this phenomen was done by Kira the ’Death Note’ user.

The moment the system try to kick him out Ren’s trap card Nemesis Authority will automaticaly activate and return this banishment to the ex-leader.

About the babies I want to suggest that you can let them live without killing them since the babies are innocent and they shouldn’t carry the sins that the scummy male parents had done. A solution for the fact that they are born from men that have many defect in their DNA, since they aren’t the ideal in their aspect based on the fetish that Yuuji had, i propose that you cut it with Absolute Cutting so that are free from the DNA of the father making them more similar to their mother (this situation is very similar to what Vandeliu did in the reincarnation of Pauvina from the novel Death Mage) because I think its a bit traumatic for the girl after what they suffered.

I’m sorry that I’m sending this comment after about a month since the pubblication of this update. I wanted to suggest the pokemon Hisuian Samurott since it is a starter, in particular of this region, but I can’t explain how it will evolve in the water/dark type since it can be done only in Hisui region. The reason for this suggestion is becouse while I was doing a marathon of Pokemon Adventures I saw that Blake’s Dewott was polishing its own scalchops, this object in the anime was also used to protect the user from grass and electric moves, after every fights to sharpen the shell edge. Also in the Sword and Shield Henry was seen repairing many object Pokemon use in combat. I prefer this Pokemon since it can regenerate the shell even after it broke like a nail while Bisharp Head blade can’t be recovered if it is chipped or damaged like in a “fanmade?” manga, that shows mini parts of all Pokemon of Unima Pokedex, I saw that an Fracure broken tusk couldn’t regenerate even after its evolution. Ironically the Haxorus was fighting Kyurem a pokemon that isn’t siymetrical from right to left.

If you are going to evolve Kubfu in Rapid Strike Style Urshifu I suggest the the technique of Seikūken from “Kenichi: The Mightiest Disciple” since it can be useful for a fighter who has its qualities. I don’t know how to implement since our protagonist doesn’t have memory of his past life, but this is something I suggest. At most this technique will be something he self taught during his six years of school or something he supposed but didn’t put on practice since this is a high level technique he isn’t sure to learn it by himself.

I prefer a classic, like Tohka Yatogami but I inclined to choose Mio Takamiya, because we are talking about Spirit.

About the weapon spirit vestige it remembers me the novel “Valhalla Saga”. I don’t remember well but I think there was something similar there.

This training field created magicaly is one of the function I would like to see to make Emiya Shirou more versatile in other fanfictions but I still haven’t found anything worthwhile at the moment.

Your idea about the spirit in the weapon is very good. I want suggest some ideas from “Reformation of the Deadbeat Noble”: I found they have something very similar to a Magus (thaumaturgy) in the novel/manga and the protagonist Irene Perreira can magicaly create a copy of his friend to learn their sword style in some training field he created with his magic similar to a Reality Marble.

You must remember the wuji of the taoism! I’m not very knowledgeable but when I searched about Pokemon they say there is the Tao Trio about Reshiram, Zekrom and Kyurem.

About Celine I remember that, since you are going to give her a defensive Sacred Gear, there is a maid in the novel/manga “I Was Caught Up In A Hero Summoning, But That World Is At Peace” that could move herself even in a “suspended time” without caring about the Law of Time governed the Goddess of Time. Ein, the maid, stated that a true maid will not be bound by anything other than her master.

We can also branch out with Han Xiao’s (fron “The Legendary Mechanic”) mechanical skills and then combine with the technology of CADs from “Mahouka Koukou no Rettousei” in Informatics skills to fuse technology and magic.

Since we are talking about people from other worlds I put in also Grid from “Overgeared”: while he has many problems like Weed for his personality, we can’t deny that many of his creation are useful.

About cooking sculpture (since in cooking you have also to learn the plating of the food) he can integrate Weed skills from “The Legendary Moonlight Sculptor” and then improve it in other material like wood, stone or minerals.
