To date, I've entered at least more than five Portals, if I included the Portal which Yumiko produced to escape back then and the Principal's own Portal which allowed him to travel from one place to another.
Though those two I've listed could be said to just be Teleportation Skills like the one Fleur used before, they're still cracking the space to arrive someplace else.
Looking at this Portal, like the one in the World of Spirits, there were also tubes connected to it which filled more tanks of Dark Energy aside from what was being filled by the Converter. Well, this one's spewing out more Dark Energy than what can be converted from a Level 1 Source Energy.
At the edges of the Portal, the spiral sparks could still be seen as they still kept trying to widen it from the other side. If I pass through this, I will surely be met by whoever's in charge there.
