S1·E2 Presea, the Master Smith in the Forest of Silence

Guided by Clef's words stuck in their head, they reach the Silent Forrest. They are dropped off by the big griffin like bird, and wonders how the hell are they getting into the mansion like place, when it's surrounded by a wall with no doors.

Fuu suggests on knocking. Umi is very skeptical, but when Hikaru starts to knock on the wall, a door opens. They try to call for someone, but no one is greeting them. They have little arguments on not being rude, and decide to enter without permission. They do not know it, but a monster crawling in the ground, manages to get in while they walk in.

The door shuts, and they enter the mansion. They wonder around a bit, until they hear noise coming from a room. It turns out to be a library, and they see mess coming from someone behind the chair. They ask if the person is Presea, but the person turns around. It turns out that the ""person"" is a cute Pikachu/Hello Jitty cross cover called Mokona.
