Supposed 'Goddess' of Water nearly drowns?

Aqua

Woohoo! Last one in is a rotten egg!

Aqua

I'll show you all how a goddess swims!

Megumin

Uh, Aqua? Maybe you shouldn't go in so fas-

Aqua

Help! I forgot how to swim!

Aqua

This water doesn't respect me as a goddess at all!

Satou Kazuma

How can a water goddess possibly drown?

Satou Kazuma

Darkness, looks like it's your turn to play lifeguard.

Darkness

I shall bravely throw myself into the dangerous waves!

Darkness

The risk of being pummeled by the merciless ocean... How thrilling!

Megumin

Fear not! I shall save Aqua with the power of Explosion!

Satou Kazuma

Why do I always have to clean up these messes?

Satou Kazuma

So much for a relaxing beach day...

Aqua

My hero! I knew you cared about me, Kazuma!

Aqua

Now, as a reward, I'll teach you my secret beach technique!
