The 20 minute gap in security began.
While surrounded by rectangular parking garages in District 11's warehouse district, Unabara Mitsuki focused on the obsidian knife in his pocket.
He wasn't going to have a chance to contact Accelerator and the others in Group.
Even if he did contact them now, there was no guarantee that they would be able to rush over right away.
From what he could hear Saku Tatsuhiko saying into his radio, the mercenaries were apparently throwing ropes up to secure the pathway. He looked through a pair of binoculars one of his supposed "comrades" passed him and saw several human figures climbing up onto the outer wall.
(…I have no choice,) thought Unabara.
The Spear of Tlahuizcalpantecuhtli was a projectile-like spell that reflected the light of Venus and disassembled whatever the reflected light hit. Whatever the light hit would be disassembled, but it could not attack multiple targets at once.
(The main problem is what to use my one attack on.)
There were 5000 mercenaries.
Turning the spear on them was meaningless. That would do nothing but leave him 4999 enemies.
He could aim for one of the main members of Block.
He thought that taking out Saku who was acting as commander would have some effect, but the plan seemed too far along to be completely stopped by taking out the leader.
(I need to aim for something that will have more of an effect…)
Unabara removed the binoculars from his face.
(What can I attack that will cut them off in one blow…?)
He moved his gaze completely away from the mercenaries scaling the outer wall.
He was assaulted by an intense feeling of tension, but he didn't have time to hesitate.
(There!!)
He pulled out the obsidian knife.
He was aiming the light of Venus towards…
The nearby parking garage.
Saku Tatsuhiko and Teshio Megumi merely stared at Unabara when he pulled out the obsidian knife. They had no knowledge of magic, so they had no idea what he was doing.
However, their imaginations filled in the blanks when they saw him start running towards the building followed by the parking garage suddenly beginning to collapse.
There was a loud dull noise.
The parking garage made of reinforced concrete Unabara was running towards began to disassemble as if the pillars holding it up were being removed one by one. As the building materials struck the ground, they smashed the asphalt sending dust into the air.
"Wha-...? Yamateeeeeee!!"
Unabara heard Saku yell at him from behind.
Shortly thereafter, he heard the metallic noise of multiple guns being aimed.
Unabara ignored them and ran.
With a clattering noise, the giant pieces of concrete rained down like in a cave-in. Those pieces protected Unabara's back from the rain of bullets. The electric cars were crushed in midair and sharp edges struck the ground. The one bit of good fortune was that the cars didn't use gasoline and therefore did not explode.
Unabara aimed the obsidian knife down lower.
He destroyed the ground using the light of Venus and jumped into the sewer in order to protect himself from the falling concrete.
However, the amount of building materials coming down was simply too great and they started flattening the sewer itself down towards Unabara.
"Ooooohhhhhh!!"
He started running, tripped and fell to the ground, and then started crawling forward.
Finally, the collapse of the parking garage was over.
The shock must have damaged the sewer all over, because it had caved-in making it impassable both behind him and in front of him.
The roof above him had been destroyed letting some bright rays of light in.
Unabara put his hands to the wall and started climbing up while looking up at the blue sky above.
And there he saw…
