Not sure if any of the TiTS devs check this thread, like the CoC2 dev team check the equivalent CoC2 thread, but I'd like it if a player character with the maximum intelligence quotient for the player character's level (so 5 at level 1, 10 at level 2 ... 50 at level 10 etc) could also be able to do the "Fix Machine" option when rescuing Kiro for the first time, especially considering the "Fix Machine" option is literally just this:

Not sure that replacing some wires and hitting the machine with a spanner really necessitates only being able to be performed by the "Tech Specialist" class, at least in my opinion.
Like, as I said, pretty sure a Steele with maximum intelligence for their level should theoretically also be capable of doing that.
Another reason is that a Steele with intelligence quotient of over 40% for their level is also able to fix Aina's toy, despite not being a "Tech Specialist", so I'd say the same could apply in this instance with fixing Kiro's machine (either via a threshold to be determined by the devs, like intelligence above 80% for the player character's level, or just maximum intelligence for the level).
