No.847 by János Mikitovics – Four-men with non-standard twin. (JV)
Definitions:
Anti-Circe: After a capture the capturing piece (Ks included) must immediately be removed to its game array square (necessarily vacant, else the capture is illegal). Captures on the rebirth square are allowed. Game array squares are determined as in Circe.
Circe: Captured units (not Ks) reappear on their game-array squares, of the same colour in the case of pieces, on the file of capture in the case of pawns, and on the promotion square of the file of capture in the case of fairy pieces. If the rebirth square is occupied the capture is normal.
Circe Clone: When a capture is made, the captured unit (except a King) takes the nature of the capturing unit and is then replaced on its rebirth square if it is empty; otherwise, the captured unit vanishes.

I like very much the part (a) with the “follow-me” pattern! Though the play and mates are different, not sure if the clever part (b) adds much to it..
I also like this problem very much. Chasing wR by bR in (a) is visually appealing. In (b), bK moves within wK’s territory (3. Kd5-c4) is unusual and surprising to me.
This is also an instructive example for showing basic mechanism of AntiCirce condition (checkmate by bK is realized by occupying wK’s home square).
Thank you for showing this fantastic problem!
I’m pretty sure that I’ve seen such mates somewhere, perhaps it was hs#4 with w&b promotions into Rooks.
Big DB partially confirms:

Thank you, Nikola and Juraj, for further information about related problems.
As for the problems mentioned by Juraj, I found the last two in PDB server.

Actually, the same mechanism is used in these problem.
