Tokyo Ravens - Volume 12 - Chapter 5.5

Part 5 
Hama avoided main roads as much as possible as it moved. 
The Onmyou Agency had withdrawn, and Hama had applied stealth magic to the entire vehicle body. It raced at full speed towards the contact point that Touji had told Amami without being noticed by any Mystical Investigators. 
Tenma was in charge of driving, and Kyouko had returned to the passenger seat. Natsume, Akino, and Suzuka were in the backseat. Touji hung onto the railing by the back, responsible for watching their rear. 
Their reunion a year and a half later. As well as a reunion they had risked their lives for. Everyone had heaps of things to say, but they were all silent right now. 
One reason was that they were exhausted after the intense battle. 
The other reason was-- 
"Ah." 
Akino, who had materialized her rabbit ears, looked towards the same place as she had the previous few times. Everyone looked along with Akino. 
All of them had repeated that action after the battle ended. Hama didn't know why, but he could perceive that area no matter where he moved. As expected, Harutora and the others were nearby. 
"Akino?" 
"S-Sorry, I still don't understand it, but even so, it feels......" 
No matter how many times she called out to her, Akino replied the same way. Regardless of how uncertain she was, she kept staring at the same place. 
"Master." 
Hama hesitated over whether to report or not, then said with a calm voice: 
"After the recent battle, I have confirmed that the 'Type AR4 Guardian' positioned nearby has had abnormal magical energy fluctuations. I'm still in contact with it. I speculate that a spiritual disaster has occurred." 

"A spiritual disaster?" 
"A 'Guardian'...... Isn't that a mechanical shikigami used to predict spiritual disasters?" 
Suzuka gave an affirmation from the side. 
Touji mostly understood the contents of their conversation from where he was in the back. 
"What does abnormal magical energy mean, exactly......" 
"The magical energy that the Guardian is releasing is far higher than its original threshold. I speculate that spiritual power has flowed into it from the outside, but the source is unclear." 
"Flowed in from the outside? Is something like that possible?" 
"In order to make timely observations, the Guardian itself has a spell that takes in magical energy from the outside. But the amount of magical energy I observed just now was more than the total magical energy the Guardian absorbed. The only possibility is that 'something else' was also absorbing magical energy." 
"Hey, hey, who made this mechanical shikigami?" Suzuka asked curiously. Touji was also interested in that, so Tenma started to introduce Hama. 
But when Natsume looked anxiously at Akino, everyone quieted down one by one and looked at the same place as Akino. 
"......That's a spiritual disaster, isn't it......" 
Suzuka hugged her knees, silently looking over with Natsume and Akino. Kyouko looked at Natsume and Akino worriedly. 
The friends gathered here continued along the road on Hama. 
The road in front of them was lit by artificial light, painting a mandala of interwoven light and darkness. 
Natsume and the others wouldn't learn about the spiritual disaster chain reaction - the Phase Four - happening nearby until the next day. 
On that night, the spiritual face of Tokyo started to change. Just like the last night of Pacific War's final phase, during the great spiritual disaster that completely disrupted the city's spiritual balance.
