Magic Tree House

A Certain Magical Index: Le Film - Le Miracle d'Endymion
Ce qu'ils partagent

What A Certain Magical Index: Le Film - Le Miracle d'Endymion is
Technically, it's about a girl with a voice that could trigger an interdimensional quarrel, but mostly it's about hanging out at a space elevator. Touma, Index and a newcomer are enjoying the view when a magic-user shows up to spoil the vibe. All they wanted was a nice afternoon, not a plot device.
