Last time I did clear H9-6 before Wishadel and Ela were added in game. Checked that I done using training permits, meaning I didn't complete stage properly.

So here Laterano only clear! Exe2 holds like champ at bottom and only needed help against flying while Exu2 explosion talent gave that extra damage for Insider to hold bottom and Lemuen sweeps everyone with S2 including Mandy, leaving only invisible enemies as real danger by the end.
