Tsutomu Senkawa, who just wanted to quickly pick up a drink, finds himself in the middle of a fight between an alien and a Space Federation officer.

Tsutomu's big day has arrived, where it will be decided whether he passes the school entrance exam or not. However, Birdy wants to settle her "alien affairs" first, which he doesn't like at all.

After Tsutomu transforms into Birdy in front of Natsumi, he tries to avoid her. However, Natsumi wishes to know what's going on and invites him to an amusement park. But one of Ms. Revi's men is already waiting for Birdy there...

As Birdy had already suspected, the sample was the serum that mutates people into monsters. She now has to hurry, because Hikawa is about to distribute it throughout Tokyo...
