1 - It's fucking Flammie, your adorable AF companion and airship.
2 - The only things that matter are sword skill of Boy and the Dryad levels of Sprite and Girl. And maybe some of the other buffs on Girl. That's IT. The whole game is fun variety with 8 weapon types and 7 elements per spellcaster but unless you've actively been raising your Dyrad level on purpose, it's level 0 which means the duration of Mana Sword is like 4 seconds. And NO ONE levels Dryad does, outside of using foreknowledge and metagaming -- seriously! Sprite gets Sleep Flower (2 MP) which is a silly debuff when you can just nuke something outright with a leveled element, and Burst (4 MP) which deals just as much damage as a 2 MP spell for another school. Girl gets Reflect which reflects even her own healing/buffs, and Revive which doesn't happen often by the time you get Dryad.
So now it's Boy who gets to strike at your pet for tiny ass windows and the girls who should be able to help somehow else are stuck just being Boy's Cheerleaders.
3 - Oh, and Mana's dead now so RIP(?) Sprite. ---
