The first battle where I use another party member! (although technically Rektina is a summon, so...) It is possible to beat Haishera with Selika alone, although there really isn't much benefit to that now that the primary source of EXP gain is the Hades Blade ticking in battle (cursed equipment) and the fact that I'll lose a good chunk of curative items.
Rektina is brought in solely for healing purposes and being a decoy for Selika so she doesn't do any attacking... but Selika is certainly strong enough to cover his own front on that end.
