Is there any way to open this PS2 3D model?

I want to open this 3D model from the PS2 game Digimon World Data Squad, but I haven't been able to open it with anything. Can anyone help me?

Looks to me like animation curves:

Here you can see something, but I don't know how to find the faces.

Hi Reh! (Reh from former Xentax?)

PS2 models are known for using auto created faces. Doesn't work here, so maybe a split up of this mesh is required?

edit: tried steps of 120 vertices but even this obvious head gives a bad result when using fake faces.
