Based on the theme and time of posting, this is likely a design for Yuki Miku (2024). Haven't found any matching entries though. The artist has a Piapro account but no uploads on it. Considering post #8243229 which is also likely an entry for Yuki Miku (2025), these are probably the artist's own designs. Either they posted it on Piapro and subsequently removed it or they never submitted an actual entry and just drew it for fun.
It is admittedly confusing because Emperor Xiaowen on Tuoba Wei and Cao Rui had the same era names, but judging from the commentary this is supposed to be Cao Rui of Northern (Cao) Wei and not Tuoba Wei, which the tag Northern Wei refers so. Retagging appropriately.

The commentary is actually quoting the (Tuoba) Wei Shu, and is describing events from Tuoba Hong's reign up to his death at the Gutangyuan imperial abode, so retagging as Northern Wei.
Fun fact: later in the same chapter, we see a similar illustration where Ikumi sacrifices herself to defeat a mirrors offshoot using the Kimochi of sadness, and that illustration portrays them in the same positions as this one. Furthermore, in a later chapter, we see Infinite Iroha face down Winchester in another illustration that portrays them in similar positioning.
