Starts out with Mamimi playing some handheld videogame about burning stuff to
please a dark god Cantide. Mamimi is obsessed with this game, which is probably
related to her past, when she burned down her elementary school, which was also
when she met Naota's brother, who saved her. Mamimi rescues a small cat that she
calls Ta-Kun (also her nickname for Naota).
Canti is now living with Naota, and Kamon is using him to run errands, do work,
and all sorts of crap. Haruko, the maid, barely does any maid-like work. During
Canti's free time he wanders to the site of the burnt school yard, and is
collecting small pieces of the back of his head. Mamimi sees him, and mistakes
him for the angel, Cantide (cause he has a little halo thing on, and some small
wings). Hence, she names him Canti.
Haruko uses Canti to take x-rays of Naota's head. She reveals that his head is
empty, and all that is left is a black hole type thing. Haruko also reveals
herself to be a part of some space organization. A new horn is growing in Naota.
Haruko gets on her vespa and drives towards the MM Plant in town. She crashes
into it, and is detained by two guards. She makes the comment that the MM plant
is not a place where people work, as there are no doors or windows. Naota comes
to Haruko, gives her a spare part for her vespa (a small gundam), and they drive
home.
Fires have been popping up all over the city, officials suspect it to be arson.
blah blah blah, Naota and some of his school friends go and visit the site of
one of the fires, some boat house. One of the guys (Masashi) talks about how
some people say it is UFOs, and how some magazine got a picture of a flying
object (Canti). Naota sees Mamimi in the river, she had been bullied by some
other kids. Naota leaves his friends and goes to Mamimi. While walking behind
her, Mamimi drops the handheld video game, and lights a cigarette. It then
clicks in Naota's head that Mamimi is causing the fires, trying to be like the
character in the game, trying to win Cantide's affection (Canti). Naota looks
up, and Mamimi is gone.
Naota goes to the burnt down school yard and seeing Mamimi sitting in a circle
of cigarettes with the Atomsk symbol drawn on the ground (think pentagram or
whatever). She is "summoning" Canti/Cantide. Canti happened to be around, and
Ta-Kun (the cat) notices him. Mamimi approaches Canti and attempts to kiss him.
Naota spazzes, the horn grows, and out emerges the rest of the robot from
Episode 1. It begins kicking the crap out of Canti. Mamimi realizes that Canti
is not a god, he is not Cantide, he is weak, and retarded.
The robots fight (pretty one-sided...), and Mamimi is thrown into danger. Naota
rushes to save her, and he does, kinda. Canti is laying on top of him, and the
other robot is moving in for a big kill. Naota calls out for his brother, and
something clicks in Canti. On his screen the sign of Atomsk shows up, and he
counters the enemy robot's attack. Then he absorbs Naota. Then he turns red.
Then he proceeds to kick the crap out of the other robot, transforming into a
gun thing. Haruko comes in to make the finishing move.
Canti expels Naota, and Naota decides that he will stay by Mamimi for as long as
it takes, that he will protect her. They leave.
Basically in this episode we find out more about Mamimi. We find out that she is
a loner, gets pushed around by her peers, is kinda delusional, and blurs
reality. Canti only reaches his prior full potential (as shown in episode 1)
when he merges with Atomsk, though some of his strength returns when the Atomsk
symbol appears on his TV. I think that this is supposed to show how the power of
Atomsk is kinda split between Naota and Canti. When Naota became scared, and
called out for his brother, the two aspects of Atomsk probably reacted to each
other, and that is what caused the Atomsk symbol to appear on Canti's screen,
which saved them from the attack.
