Hi again! It takes much time to update this story as I have many home works. Also, I'm thinking of making other one-shot stories of TrainxEve after I posted story of "Another Way".

Thank you for the recent reviews, especially from XxTrain'sCherryBlossomxX, Happy Happy Punk, Daisy19971, jeune rye, Darkness Princess Kit, and CattyGothLoli. You supported me well all this time. LUV U ALL!

Chapter 15: Lost The Key

Jock POV (on the top floor)

"He's back!" I snapped while realizing all of screens of surveillance cameras on the lowest floor and some of them on the middle floor showing blank pictures. "Damn Troy for helping him!"

Then I heard some people running on this floor.

"No way ..." I muttered when one of the screens showed three people entering this floor. A green haired man. A purple haired woman. And ….

Numbers' Captain?

They entered from the wall that Black Cat broke, and then went upstairs to the top floor. Facing this situation, I called Adam so that he would come and protect me.

Adam POV

Hiding in the main research room, I leant my back against the wall.

I felt annoyed when my phone was vibrating. I saw Jock's name on the screen, and then rejected his call. I knew he called me for protecting him, like I did before. I was the one who had many ideas to make tools to overpower Numbers' weapons, after all.

Orihalcon was a rare material. Even though I had an ability to transform, it was difficult to change my body part into an orihalcon thing. Instead of it, I asked Jock's helpers to make giant fans so Troy's people could use them to beat Jenos Hazard, making his Excellion useless. Then I asked again to make freezing guns to take care of Number X's Seiren. However, not all of Numbers' weapons had weakness. Sephiria's Christ was a good example. Reading her file, I knew her abilities and experiences. I was sure she would be a tough opponent if I fought her. Well, it was not that I was afraid of her, but I didn't want to protect Jock at this time. In fact, I hoped that Sephiria, Sven, and Rinslet would capture him. I felt like I could predict what would happen. Bad news for him. Good news for me.

Have fun in the jail, Jock, my mind sneered while I was rejecting his call again.

"Why don't you pick it up? Maybe he or she has something important for you."

I was shocked, hearing his casual tone. It was too loud and too clear, as if he was next to me. So I turned around and gasped.

Train casually leant his back against the opposite side of the same wall with me. Hands in his pants' pockets.

My eyes widened. A few seconds ago, he stood before Eve's tank. But now, he was here, close to me. I didn't even see his move.

"Well, my ex-captain said those two sentences to me before. So that I picked my phone up when Troy was calling me," he said matter-of-factly. Then he grinned, greeting nicely, "Nice to meet you, Adam."

Jock POV

I ran fast, heading to the middle floor. Adam didn't answer my calls. Why did he ignore them? Thinking of it, there were two reasons in my mind. First: he met someone strong that blocked his way (I automatically thought of Black Cat). Second: he ignored me on purpose.

I growled, thinking the second idea. Since he offered himself to be a nanomachine boy last year, I was suspicious. I meant, who wanted to be an abnormal creature? A lab rat? A bioweapon? But he insisted, saying that he wanted to be recovered from his fatal illness. So I accepted him as I needed a human sample for my nanotechnology project.

For the early cooperation, I was happy seeing his loyalty. He made many tools to fight against Numbers, helped me in making this flying base and nano server, and protected me well. He even supported my decision to kick Troy and his father out. However, after that, he was trying to ignore and disobey me, rejecting my calls.

At this moment, I felt like he started showing his true reason why he joined me and let his body to be a nanomachine boy. He wanted to betray me, knowing that I depended on him a lot.

"Jock Morris. I find you!"

I stopped, seeing a green haired man standing in front of me. Sven Volfied. A high level sweeper. Eve's surrogate father.

"You would never be able to capture me!" I shouted, and then shot him repeatedly with my gun. As the result, dust was flying among us. My vision blurred, but I was sure some of my bullets hit him.

Realizing that I ran out of bullet, I threw away my gun and escaped.

"What!" I screamed as a net flying towards me and trapping my body. I fell to the floor, struggling uselessly.

Slowly I could see clearly again as the dust started disappearing, revealing uninjured Sven, with the exception of bandage on his forehead hit by the ruins.

"Vision eye," I growled, seeing his right eye for the first time.

Actually, I knew this ability and thought it was just a rumor. Now I could believe it was true. He could read the future, seeing that I would be trapped.

He covered his right eye again while approaching me.

"I'll take you to the helicopter," he said.

"Where are the two women?" I asked curiously.

"Heading to the controll room …" he replied, continuing, "… to land this base."

Rinslet POV

In the control room, I was speechless, seeing many buttons and screens. How could I control this base to land well? I didn't know how to operate them.

"Rins, please take all nanotech and Numbers' data at those filing cabinets. Sven is taking Jock Morris into the helicopter," Sephiria ordered. "Carry the data to the wall that Heartnet tore down. Belze and Sven Volfied are waiting for you to receive them. If you finish with them, stay in the helicopter."

"Do you know how to operate these things?"

Instead of answering my question, she spoke, "This is urgent. Just do what I ask."

I sighed and cursed silently. She was lucky now. If our situation was not critical, I would complain harshly. Unfortunately, I didn't even have much time for it. Maybe I would think of it later.

Adam POV

"Black Cat …," I murmured, retreating slowly and transforming my right hand into the sword.

He instinctively caught my battle signal when suddenly I flied towards him right after a pair of black wings appeared on my back to increase my speed, trying to cut his chest, the vital part of the body.

He shot repeatedly. Some bullets that hit my hands and legs fell on the floor without getting me injured, as I transformed my skin into thick metal.

"It's useless. You would never hurt me!" I warned him while he was keeping the distance from me.

"How about this?" He shot again, letting a bullet flying towards my head. Nervously (and luckily), I succeeded to avoid it although I could feel the cold wind on my cheek at that moment.

"Where did you aim at?" I mocked, realizing that he missed.

"My target," he replied matter-of-factly.

"Wha-"

Then I heard something exploded. When I turned around, I saw smoke appeared from Eve's tank.

Train POV

Princess' tank. It was my target, using a burst bullet. I looked at it, hoping the water would flow out. But what I expected didn't come.

"Too bad," Adam sneered, "Any bullet would never be able to break it. This tank is made from a special glass. Even a detonator can't destroy it."

"Are you saying that you have something to open it?"

He smirked, taking something from his pant pocket and showing it to me. He answered, "This is the key to open it. There is only one in this world. Actually, I don't need it. But I don't want you have it. So, I should do something."

He transformed the skin of his palm into a metal skin. Then he shattered the key as he clenched it tightly in his fist.

I was speechless, seeing the key was broken into pieces, being scattered on the floor.

I had lost the key to free Princess.

TBC …

A/N: I am writing the next chapter and hope I can post it soon. Anyway, thanks for reading this chapter. ^ ^
