Usage[]
As the surrounding area turns cloudy, a cloud begins to form, striking bright blue lightning on the field below, making both the users and their Keshin emerge out of it. Their Keshin then draws out its sword from its back, holding it by its grip with its two hands and raising it in the air, letting it be hit by another bright blue lightning strike, akin to a lightning rod. Once its sword is covered in lightning energy, the users' Keshin gets into position as the users follow suit, springing towards the airborne ball covered in bright blue energy, gathering swirls of shining and dark energy. They then volley the ball with their feet as their Keshin simultaneously slashes it, turning it into a crescent cut of bright blue lightning as it rapidly heads towards the goal.
Its dub name, Caliburn, is another name for Excalibur, which is also a reference to both its usage and Keshin.
The strength of this hissatsu technique in Inazuma Eleven GO was listed as "SS" in "Inazuma Eleven GO Shine/Dark: Nekketsu Official Guidebook Kyuukyoku-ban".
In Inazuma Eleven GO, despite Keshin hissatsu descriptions not being readable in normal gameplay, its description from Inazuma Eleven Strikers 2012 Xtreme can be found in the game's files.
In the European versions, a translated version of this description can be found (EN: Strike with a lightning blade imbued with the power of the heavens!).
