SOLUTION: HOUSEKEEPINGANSWER: HEAT SHIELD
The answers to the given clues all resolve to names; searching enough of the names reveals them as the names of characters in the game Fire Emblem: Three Houses. In the game, the player takes the role of an instructor who chooses to teach one of the titular three houses of the Officers Academy. Each student is assigned to a house based on nationality; importantly for this puzzle, the houses are each associated with a color: blue for the Blue Lions, yellow for the Golden Deer, and red for the Black Eagles (yes, red and not black). The question marks that give the length of each character's name include one of each of those three colors. To find the letters spelling out this puzzle's answer, only the letter in the place of the question mark with the same color as that character's house is extracted:
| HILDA | Golden Deer |
| MERCEDES | Blue Lions |
| PETRA | Black Eagles |
| HUBERT | Black Eagles |
| ASHE | Blue Lions |
| RAPHAEL | Golden Deer |
| FERDINAND | Black Eagles |
| MARIANNE | Golden Deer |
| FELIX | Blue Lions |
| INGRID | Blue Lions |
The correctly-colored letters spell out the answer HEAT SHIELD.
I've always found it tough to make a puzzle that is both easy and interesting, and I still don't think I've nailed the process yet. This puzzle really tested me; while it's the exact difficulty level I wanted puzzles for this hunt to be, I so badly wanted to add some other element to keep it from being so simple. The unused colored letters having no significance, the fallback on simple crossword clues as a way to identify names, it feels to me like it "needs" to be more complex. But I still like this puzzle, and a few solvers told me they loved it. I think I've had this idea that easy puzzles can still be good as long as they are complex enough, but this puzzle has made me wonder whether complexity is even a necessary part of making a puzzle fun.
