I still think my Lilty-only no master's weapon route has potential to be decent, but Selkie is inevitable for now.

1st try master's weapon 2/3 mythril in DC, 1/1 mythril in SC 4 encounters (Leuda, Brigands, Fum, Alfitaria) 66 STR with meat (1x masamune) 28 DEF (iron belt- I had enough gil to buy armor too, but I miscounted and thought I didn't)

This run can still be much faster. The backwards year 3 route still feels weird to use, but without insane drop RNG (and a big gamble in MF2) I don't think it's worth it to do it any other way.
