Heaven's Lost Property - Season 2 (2010)

Mikako organizes a snowball fight between the boys and girls. Tomoki and Mikako are made commanders. The objective is too wipe out the enemy's commander. What could possibly go wrong?

Sugata and Sohara use Nymph's Dive Game program to travel to the Synapse. In the process Sohara causes an item to fall to earth. Tomoki uses the item to build a transforming 'panty' robot pedal bicycle.

After Tomoki learns that the girls at school find him undesirable and unintelligent, the gang takes part in a quiz to find out just how smart they really are. Meanwhile, in Synapse, a plan to destroy Ikaros and Nymph is taking shape!

Even though they know it's a risky move, Astraea and Nymph decide to raid Ikaros's watermelon patch. Meanwhile, Sugata and Nymph find themselves in serious danger after infiltrating Synapse.

The time has arrived for Astraea to make a choice. Will she do the Sky Master's bidding and destroy Ikaros and Nymph once and for all? Or will she listen to Tomoki and find the strength to choose her own destiny?

During the Summer Festival, Mikako organizes a fishing contest at the swimming pool. There's only one way to win: reel in the curviest catch! Later, Ikaros tries to find the best way to spend her allowance.

Sohara teaches Ikaros about the ins and outs of marriage. Meanwhile, Tomoki puts the final touches on his summer project: a massive network of periscope-like tubing that allows him to sneak a peek at girls all over town!

Tomoki takes action when Ikaros, Nymph, and Astraea are overpowered in battle against Chaos! After the fight ends, it looks like peaceful days are ahead - until it becomes obvious that Ikaros still faces a serious crisis.

Tomoki makes a splash with the girls in swim class when he transforms into pool water. Later, the whole gang heads to a wedding - but who will be walking down the aisle?
