Koishi + Shinki = Shinki Kakushi (or you can call her Shinki Jr. due to the namesake)

While I'm wide awake at night yesterday, I get affected the Shinki bug, what I considered to be causing me Shinki fetishes today and from now on.

Shinki is a pretty interesting character with a nice design, as well as being even a more popular PC-98 character than Yumemi (perhaps second only to Mima), and with Koishi, one of the most popular Windows Touhou characters (she once reached first in the popularity poll of 2015!), a jolt of inspiration appeared in my head, and in my raving head, I think "Hey it's interesting to add a character who is like Shinki + Koishi, and I would farm at least 1000 views with that character!". And so, Shinki Kakushi is born.

Her name is the namesake of her creator and the one she calls "mom", Shinki (to be exact, Shinki also calls this character her "daughter" too, despite she is a created being rather than a biologically born being, similar to a clone). What's fun about her name is her surname can have the meaning of "hidden" (隠し), thus give a hint to her powers and their limits (more on that below).

She has a badass ability: The creation and destruction of memories. What this ability exactly do is that she can... like creating memories from the experiences of those who she knows (well, almost everyone in the game series, due to Shinki, Sr. (the one who debuted in Touhou 5) is working for God after MS' endings in my Touhou fanon, and since that she knows fairly a lot of people, and that she passed that knowledge to her creation / daughter), or even wipe it from their minds in just a few moments (Scary). The only thing is what people know of this ability is just like 0.0000000000000000000001% of her ability's power (similar to Shaggy from Kaizo Shaggy (thanks, I cited @TemmieTheTemtem for that fact)), so basically if she uses her ability at full power, it's basically "game over" for your minds: Remembering all of your traumatic experiences for all of your life and let that haunt you, or having all of your memories wiped, and you will even don't know why you existed, and thus, her surname hinted that the true power of her ability is hidden from the knowledge of others.

While she is that strong, she is still not as strong as Megumi. While Shinki, Jr. can cause severe memory loss to people, but the ability is not designed to have her kill enemies at her will (despite that some of the ones who are affected by her abilities commit suicide and died just because they even don't know why they existed), as well as her ability even does not affect inanimate objects and tsukumogami (even they have sentience and memory due to them gaining a soul (as in many stories where tsukumogami of abandoned objects came and get revenge at their owners for abandoning them, so it is suggested that tsukumogami have memories too)), or even ghosts and spirits. While that Megumi's ability (but what I listed below are from the ability of that of their sword) can destroy anything solid on Earth, and also with the ability to disconnect spirits from the cycle of reincarnation by just slashing at them (similar to Youmu's sword). Their existence alone can cause the surrounding to become serene (due to being an Angel of God), which render everyone within their victinity to have no will to fight against them (and they cannot fight and / or damage them, due to being a wholly spiritual being). While that Shinki, Jr. ability is just revolve around creation / destruction of memories, and also can be damaged due to having the vessel of that of a normal human (despite their resilience is far greater than of the strongest average human being). Due to the Angelic Triad's being the three most powerful non-God characters in the series, and their abilities are purely offensive (or at least with offensive uses while mostly being suited for defensive uses), then Shinki, Jr.'s ability could only get into the 4th place, due to their ability can only affect living beings and is more balanced in the offensive and defensive uses than the Angelic Triad (the Angelic Triad's abilities have more offensive uses than defensive uses).

Anyway, due to also being affiliated with the Holy Order of the Thaumaturgy's God, I'm thinking up which weapon (also engraved with a cross and / or crosses) should Shinki, Jr. wields, or make her doesn't use any weapon at all, just attacking with her ability. But the latter is quite confusing to create concept for her normal attacks (not Spell Cards), since her ability does not even involving creating physical objects to attack opponents with. When I think of a weapon, knives are what I think up first, but my mom has called the images of my OCs holding knives "violent" (despite that's a usual norm in role-playing games), due to I drew knives realistically (due to I've played Undertale and know how to draw realistic knives from that), also, only throwing knives can be used as projectiles, so I might have to reuse Mari's knives for Shinki Jr. (this time I have to alter their design a bit)?

Anyway, that's the character concept! Hope you appreciate this character!
