Civil Security arcEdit
Legacy of the Seven Stars arcEdit
Two days after its initial attack, the Original Gastrea knits its own web into a kite and, now located in the Outer Area—32nd Area, glides through the air as Rentaro Satomi and Enju Aihara are aboard a plane. Once Rentaro notices the Gastrea, he quickly tells the pilot to lower their altitude. However, before he can do so, Enju opens the back door and jumps out of the plane and on top of the Gastrea. The Original Gastrea is then taken down to the ground, where it regains its former size and confronts Initiator Enju Aihara.
However, much to its demise, and after putting up a short-lived resistance, the Original Gastrea is mortally crushed by Enju. Not long after, the case in its belly, containing the Legacy of the Seven Stars, is taken by Kagetane Hiruko and Kohina Hiruko.
Growth: An ability which granted the spider-type astounding flexibility; permitting for extreme size reducement. The Original Gastrea was able to decrease its body size tremendously to allow for a breezy escape, successfully being able to conceal its presence from the monitoring cameras. The Gastrea was also able to change its size to match that of a small kite, allowing for aerial transportation. The rate at which the Gastrea can change its size appears to be particularly fast.
Enhanced Strength: With a single hit of its eight legs, said Gastrea was able to push Enju away from it while at the same time preparing its next attack.
Enhanced Durability: The Original Gastrea was able to withstand a direct hit from Enju Aihara whilst in midair.
