I really enjoy its slow methodical pacing, one of those manga you could read multiple times, I may have to pick up the ln
The girls are great, the comedy is good and the world building is generic yet polished. Art is sloppy but sometimes works well, it doesn't improve so don't go hoping.
My only issue is the premise is RARELY used, the Japanese kid is just an excuse to have modern knowledge and the commander only comes out in fights. This is a story about a son of a noble and his affairs. You will not encounter lots of shounen or magic its pretty grounded. Depends on your tastes but you could* really enjoy it.
