|サテライトカノン, Sateraito Kanon|
At the start of the summon, a dimensional portal to outer space opens and leads in in the Thunder Seru, Gilium. The energy from Gilium causes explosions to erupt behind it as it raises its appendages overhead and charges a pyramid-shaped beam of energy between them. The energy then shoots up into outer space and collides with the center of a satellite flying overhead. This causes the satellite to react by shooting pillars of energy down onto the field, which creates an explosion that hits all enemies.
- Space Cannon is the most MP costly and powerful of the regular Seru summons
