[1] The peaceful sightseeing and shenanigans suddenly come to end as, in the middle of its visit at the IS Academy, White Chalice under attack by a huge swarm of robotic enemies! Defending the ship is priority. This fight is going to be tough - most of the enemies aren't too strong individually, but there's lots of them. All of them can fly.
Enemy list:
Pirateroids - the majority of the enemy forces, they use weak ranged and melee weapons and are at most a bit larger than a human. Other enemies are much tougher.
Golems - the size of an IS unit, these machines spam beams. Much tougher than their size would suggest.
Dragobulls - a bit smaller than Mobile Suits, they breathe fire and attack with fists at melee range.
Zo Whyguls - the size of Dragobulls, they spam missiles from afar. This is not Macross!
[2] Lily Rain EVE activates her Charge Mode, and you can reap the benefits! Your whole unit or some parts of it (eyes or hands most likely) start to glow with blue light, which gives it a huge power boost and can even temporarily unlock normally unavailable awesome attacks. Go to town!
This happens later during the fight. You can reject this power if you're badass and/or individualistic enough to not need or want it.
