(Continued from above):
Hiwatari asks Daisuke how he was able to open the lock. This question catches Daisuke off-guard and he freaks out. He tells Hiwatari that he has the same type of locks at home.
Daisuke returns to his home after school. After entering the front door, a trap door opens up under him, yet Daisuke doesn't seem at all surprised. He is able to catch the bottom of the doorframe before he falls, and flips himself back up. Daisuke looks out to see many laser beams in the room ahead of him. He then jumps of the doorframe into the room below. Daisuke begins to run throw the room, and effortlessly spots which laser beams aren't dangerous. He avoids the beams until reaches the end. There, he sweatdrops at the sign "Congratulations on Living!"
Daisuke walks threw the door, and before he can finish his sentence, his mother, Emiko, hugs him. She seems thrilled to see her son, and tells him how proud she is of him. Daisuke's grandfather appears. He tells Daisuke that even though he's gone through a lot of practice in the past, since it is his 14th birthday, he's training is complete.
The TV reports that a note was left at the Esvil Art Museum and the statute, St Tiasu, is now surrounded by police guards.
Daisuke goes to his room, and meets up with his pet, With. Daisuke apologizes to With for not being able to bring him to school. Daisuke holds his letter to Risa in his hands and falls into a state of depression.
In Daisuke's mind, he sees an image of Risa and hears her voice. In this vision, Risa tells Daisuke that she likes him. Daisuke is swarmed with confusion, and begins to feel something strange happening to his body. He feels an eerie warmth and feels another set of DNA within his body. The next thing you know, Dark has appeared in the room, and Daisuke is no where to be seen.
Meanwhile, at the Esvil Art Museum, Takeshi's father tells of all the security surrounding the statue, St Tiasu. Takeshi's father is informed that the high commander has arrived, and it turns out that he is Hiwatari! Takeshi watches this and concludes that he should be able to catch Dark. He also explains that this is Dark's first appearance in forty years.
Back at the house, a panicking Daisuke (who is now Dark, and at this point, in control of Dark's mind) runs to his mother. Instead of freaking out, his mother gets all giddy and tells Daisuke/Dark that he looks just like his predecessor. Daisuke panics even more and complains that his body has selfishly grown and turned into another person. His mother explains that it is his time to inherit the name of the Phantom Thief Dark.
Emiko(Daisuke's mum) explains that every generation of Niwa men turn into Dark once they reach the age of 14. Daisuke has trouble excepting this and wishes to be changed back. His mother, however, tells him that she has already sent out a warning to the museum, and that he is to steal the St Tiasu statue.
Daisuke realizes that this is what Takeshi was all excited about earlier. In his mind, Daisuke still has trouble excepting the situation. His grandfather then explains that he is the only one who inherited the blood. Therefore, since he was a child, he was put into situations which would allow him to become the Phantom Thief. He also explains to Daisuke that the key to his transformation is the holy maiden.
Daisuke figures that talking the St Tiasu will change him back. His mother tells him that With has been Dark's accomplice for years, and that With will assist him. Daisuke places his hand on With's head, and With acts as black wings on his back.
Daisuke takes to the sky and heads towards the museum. He hears the bells signaling that it is eleven o'clock. Daisuke spots the Esvil Art Museum and is shocked when he sees the amount of guards that are on duty. The guards, Takeshi, and the TV reporters spot Dark in the sky. They brace themselves for his arrival, then panic when they lose sight of him.
Daisuke lands in a nearby tree and gets ready to steal the St Tiasu. The lights dim, and when they come back on, the statue is gone. All the guards begin to run around and panic. Daisuke (who is still Dark, by the way), dresses up as one of the guards and attempts to blend in. Takeshi's father questions him, and Daisuke states that he is remaining near where the statue was to stay on guard. Just when Daisuke feels that he has gotten away free, Hiwatari appears behind him.
Hiwatari shocks Daisuke by saying that he thought that they (Hiwatari and Dark) would never meet again. Daisuke tries to figure out what Hiwatari is doing at the museum, and speaks to Hiwatari. It would seem the Hiwatari knows all about Dark, and the trickery he uses to steal artwork. Daisuke calmly replies, but the next thing he knows, Hiwatari flips him over onto the ground on his back. Hiwatari positions himself over Daisuke (reminder: he's still Dark) and brings his face close to Daisuke's.
Daisuke begins to panic, then realizes that Hiwatari has placed handcuffs on his wrists. Daisuke begins to question his actions in his thoughts, when Hiwatari replies without being asked. He explains that to the normal person, he is nothing. He tells Daisuke that all he wants to do is catch Dark.
Daisuke begins to panic in his mind. He didn't want to steal the artwork. He just stole is because he thought that it would change him back. Daisuke doesn't like the idea of going to prison and calls out in his mind.
Daisuke's body begins to send out a bright light and energy. Hiwatari is taken back and watches. Daisuke is confused even more and complains of feeling pain. In his mind, Daisuke and Dark separate their thoughts and become two separate individuals.
Dark calls to With, and With transforms into another Dark. Before Hiwatari now stand two Darks. Hiwatari cannot believe his eyes. A guard from behind calls him, and as he is distracted, Dark(s) escape and disappear from sight. Hiwatari concludes that this will be an interesting and long battle.
Dark stands a top a building. Within Dark's mind, Daisuke complains that this isn't the right thing to do. Daisuke and Dark share a single body. Even though Dark is now in control, Daisuke is still awake in the back of his mind, yet is unable to do anything but speak his mind. Dark and Daisuke argue some more, but are interrupted when a door opens.
There stands Riku, Risa's twin sister. Her eyes widen as she sees Dark, and Riku screams "Pervert!" Then she calls her sister, and Risa comes and searches for the source of her sister's screams.
Daisuke finds himself in a water drainage system soaking wet and feeling cold. He realizes that he is "Daisuke" again and is in his own body. He goes over his situation in his mind.
Daisuke returns home and is greeted by his mother and grandfather. They are thrilled that he was able to steal the St Tiasu. Daisuke refuses to steal anything and go threw that again. His mother tells him that it's impossible because he loves Risa. Emiko explains that Dark's DNA reacted to his feelings of love towards Risa. That's why he transformed into Dark, and how he was able to change back.
Daisuke yells at his grandfather for lying to him. The grandfather re-states that it's due to holy maidens. Daisuke contemplates this, and has trouble believing that Risa and Riku and these maidens.
Daisuke goes through everything in his mind. It's a lot for him to accept. He concludes that much trouble lies ahead in his love life. And that this is a problem truly difficult to solve.
