Having grasped the basic background of this world and identified NERV and the Angels as the main targets of observation, Osiris II did not rush to take action.
He needs more specific and direct empirical data to assess the true performance and potential value of these unconventional entities.
He remained invisible, moving through the seemingly ordinary yet abnormal city of Third New Tokyo, his sensors constantly scanning for various signals from both above and below ground.
His passive monitoring network first detected anomalous energy readings from the city's outskirts.
A high-intensity energy source with clearly hostile characteristics is rapidly approaching.
Almost simultaneously, piercing air raid sirens blared throughout the city, and the public address system began repeatedly broadcasting emergency evacuation orders.
The few pedestrians on the streets vanished instantly, and the entrances to the pre-designed shelters opened one after another, with the entire city switching to a state of high alert and wartime readiness in a very short time.
Amid this emergency situation where chaos and order coexisted, mobile sensors located an individual exhibiting abnormal behavior on a street leading to a designated shelter.
It was a thin boy, wearing an ordinary school uniform, walking slowly alone on the empty street.
His direction of travel deviated from the emergency signs, his movements revealed obvious confusion, and he seemed out of place with the efficient emergency system around him.
Osiris immediately focused some of his observations on this person.
In the magnified image from the optical sensor, the boy's head was lowered, his eyes were unfocused, and his shoulders were slightly tucked in.
These body language messages are very clear: isolation, self-isolation, and a clearly unstable mental state.
Minors wandering alone during this crisis exhibit behaviors that are out of sync with their surroundings.
A blue car screeched to a halt beside the boy.
Osiris quickly compared the facial features with NERV's publicly available personnel database and confirmed the identity of the person who got off the vehicle: Misato Katsuragi, a member of NERV's Tactical Operations Department.
Just as she was about to speak with the boy, a shockwave from the battle between the Angels and the Allied Forces swept in from afar.
The violent explosion occurred at a street corner not far away, with flying debris and building fragments hitting the side of the car.
The windshield has spiderweb-like cracks, and the right door is visibly dented.
Misato Katsuragi quickly shielded the boy behind her while rapidly checking the condition of the vehicle.
After confirming that the engine was still running, she immediately got the boy back into the car.
The damaged blue sedan emitted an unnatural roar, but was still able to move.
The vehicle drove away from the dangerous area with a slight bump and soon disappeared at the entrance of the dedicated passage leading to the underground NERV headquarters.
Osiris recorded this information: NERV member Misato Katsuragi has a special connection with the boy and prioritizes his safety during any crisis.
Despite being affected by the battle, the vehicle retained its basic driving ability and eventually returned to base safely.
The boy's exact identity still needs further confirmation, but his importance is beyond doubt.
Osiris turned his attention to the ongoing offensive and defensive battle on the city's outskirts.
The Allied Forces' combat units have been fully deployed, and dense artillery fire has created a continuous barrage of explosions around the Angels.
The main gun fire of the tank formation stirred up ripples of energy on the surface of the AT force field, but it could not penetrate the seemingly thin diamond-shaped barrier.
The precision-guided bombs dropped by the fighter jet formation exploded into dazzling fireballs on the force field surface, and the shockwaves shook the surrounding buildings, but the Angel itself remained unharmed.
With conventional weapons rendered ineffective, the command deployed its last trump card.
An N2 bomb was detonated directly above the Angel, and a massive fireball instantly engulfed the entire block. The intense flash forced the observation equipment to activate its protective filters.
The shockwave swept through, shattering all the windows of buildings within a radius of several kilometers.
However, when the smoke cleared, the Angel remained suspended in place, and the AT field did not even show a crack.
The battle lasted from daylight until nightfall.
The coalition forces tried various tactics: concentrated fire of armor-piercing rounds at the same point, long-range sniping with electromagnetic guns, and even bunker buster bombs in an attempt to break through from below, all to no avail.
The Angel seemed completely unconcerned about all of this, and continued to advance steadily toward NERV headquarters, occasionally waving its whip-like tentacles to easily destroy the defensive fortifications along the way.
When the Angels broke through the last line of defense and began to directly attack the upper structure of NERV headquarters, Osiris detected a strong bio-energy reaction coming from underground.
The launch silo opened with a roar, and the purple-green Unit-01 burst through the ground under the force of its immense thrust.
Osiris' sensor immediately began full-power scanning, focusing on analyzing the way biological tissues and mechanical structures are combined.
Based on the sensor feedback regarding the machine's reactions and its extremely unfamiliar and sluggish movement patterns, Osiris judged that the pilot of Unit 1 was clearly an inexperienced novice, or that the machine itself had serious compatibility issues.
Faced with the Angel's agile yet deadly light whip attacks, Unit-01 could only clumsily parry and dodge, its thick armor constantly emitting blinding sparks from the hits, making it seem utterly powerless to fight back.
Just as Unit-01's left arm was entangled by the light whip and the armor emitted a teeth-grinding twisting sound, Osiris successfully cut into a secondary encrypted channel of NERV's internal communications.
The channel was filled with tense commands and reports.
"...Unit-01's left arm is severely damaged!"
"The synchronization rate has dropped sharply!"
Shinji! Hold on! Try to break free!
The name "Shinji," combined with the fact that the boy had been urgently brought to NERV headquarters, quickly led Osiris to connect the two.
The driver was that seemingly fragile and confused young man.
Almost at the same time the pilot's identity was confirmed, a dramatic change occurred on Unit-01.
After its left arm was brutally torn apart and the machine collapsed to the ground emitting painful cries, the sensor readings instantly exceeded the safety threshold.
The biosignals inside Unit-01 became violent and chaotic, and the energy output curve spiked at an unusually steep rate.
Its pale green optical sensor suddenly turned an ominous blood red.
Then, the massive titan stood up on its own, seemingly without any human control, and emitted a superhuman, terrifying roar.
Its behavior pattern completely changed, abandoning all tactical maneuvers. With speed far exceeding its previous limits and pure beastly instinct, it pounced on the Angel, tearing apart the AT field that had once blocked all conventional firepower with its bare hands, and then frantically biting and ultimately destroying the Angel's core with its teeth.
The entire process was filled with primitive and savage violence, which contrasted sharply with its image as a sophisticated weapon.
Osiris fully recorded the energy peak, biosignal characteristics, and the process of devouring the Angel's core during the berserk state. At the same time, he archived the pilot's identity "Shinji Ikari" in relation to the observed instability and potential dangers of the machine.
After the battle, the city fell into an eerie silence.
Osiris began to systematically integrate the collected data.
The biomechanical fusion technology and AT force field application demonstrated by EVA represent a highly valuable research direction.
As a biological weapon, the core structure and energy system of the Angels are also of great research value.
However, the instability and potential risk of loss of control exhibited by EVA should not be ignored.
These findings provided crucial information for subsequent action plans.
Given the inherent combination of technological value and risk, simply observing is no longer sufficient to fulfill the mission of exploration.
Acquiring these technologies is of strategic significance for enhancing the technological strength of one's faction.
Osiris concluded that it was necessary to contact NERV.
Directly seizing the technology by force is too risky. A better strategy is to find an opportunity to demonstrate one's value and gradually acquire the technology and data through cooperation.
The attack by the Fourth Angel provided him with initial bargaining chips and ideas for intervention.
He needs to wait and plan the initial contact strategy.
