"Wow! So you know what will happen in the future!?" "Not too much but yeah, some event..." "And I have ability to know when a new neighbor will attack?" "Yeah..."So... I ended up telling her indirectly that I'm a regressor by telling her I knew some events from the future. I also ended up telling her about neighbors and the neighborhood.

Just a moment ago she came here bombarding me questions about what happen yesterday. She entered at our backyard that is why she saw my training materials. I just answer all of her questions.

"But Osamu-kun, isn't what are you doing dangerous?" She hesitantly asked. I turn to her serious. "Certainly that is why I don't want to drag anyone, but don't worry I had the bail out system to teleport back here"

Chika was still worried for me even I say that. "Additionally, mom support me and give all things I needed" Chika once again wince a little.

Wait... Does she perhaps wants to come!? I realized.

She look at my expression and says. "Osamu-kun, you don't have to push yourself harder! If,if I have anything to help then I will try! Even I have to risk my life" She pushed. I look at her, thinking my life decisions. She really wanted to come.

I just breath in and out. "Do you know how to pull a trigger of a snipe?" She look at me tilting her head.

'What kind of idiot I am!!!? Asking a little girl if she can shoot!?Aah!'

"Um, yes I can"

'Whaaat!? She can! Are you serious!?'

"I have learn in mobile RPG games. I'm not really sure if I can apply it in real life"

'Oh, I'm really dumb'

"But I guess it was okay right Osamu-kun?" "Well yes that's enough" I put my hand to my chin.

If I let Chika to be a melee attacker then she will get hurt more, but I guess I will equip a kogetsu to her trigger. I'm not fully sure if I will make her a sniper or a gunner since she can hide here trion level with that. Bullets is not an option since Meteor, Asteroid and other bullet trigger will fully reveal her trion level. But in my past life, bullets have a can really deal damage to enemies since it was once Chika's hidden card.

'I guess I will create a trigger with a kogetsu, a lightning, lead bullet in case(since Chika can't shoot people),Igris, shield, bagworm,the bail out system, and finally an asteroid. I will just say Chika to not use it as much as possible.'

"Alright then, are you really sure about this Chika?" Chika just nodded with heart content. "Okay then, just like I told you. There will be an attack exactly a month from now, that is why we will practice fully! Are you sure you can take it?" "I will try to take it!" "Well then let's start now!"

.

.

And for the rest of the month me and Chika trained harder. I also created a black mask with voice changer for her too. And since I already have some trigger with different trigger equipped I just teach her all of the functions and the way how she use them. We both also have different training schedule. Her training was a lot more easier than mine and fit to her age. Except for jumping from building to building training.(It was totally not allowed for them but they learn to sneak okay)

And finally the day has come.

We stand above a tall building wearing our bagworm but with a hoodie to at least cover our hair, we also had a black mask with each other, since we will fight everywhere the city I remove my glasses and replace it with a goggles made of trion so it won't blur our way just like Chika.

Seemingly the day looks like normal, not until the dawn.

"Chika,it's starting get into position" "Got it"

It started from a small black ball appeared in the west, until many portal opened one by one at the sky covering the majestic sight of the dawn. As expected many people didn't able to resist to look at the black portals opening. Many thoughts it's just a show but when the trion soldier came out, they started screaming. The monsters started to destroy everything in its way. "Help!!!!!""Ahhh!!!" "Help me!" "Monsters!"

"Please help!" A mother shout hugging her daughter. I, then barged in and defeated the marmoid in just a split of a second. "Are you okay?" "Um.. Yes! Thanks!" "Evacuate at Seirin School Academy!" I ordered as I move next to the next neighbor and save more lives. The only order I give to Chika was...

Shoot every trion soldiers you see, everytime you see someone tell them to go to Seirin School Academy immediately, you know first aid so you can also help at applying med kit to a hurt citizen and specially if you have seen anyone fighting the monster back with a border written in their emblem, you should run and inform me through com.

Chika was in the East while I'm in the West so fighting will be no worries to both of us. As I remember Jin-san and other old border will usually focus at North and South since they have more enemies to kill there and also the invasion starts there.

Since my trion increased in unknown amount, I still need to make sure I won't run out of trion.

"Please anyone! Help! My sister!" A shout take my attention and run towards the direction. I quickly saw a big bamster trying to crash a woman. Osamu just didn't hesitate and quicly defeate the bamster. "Hey! Are you guys okay!?" "Yes! Thank you!Thank you! Thank you!" a boy said.

Recognizing the voice I turn around to see a recognizable person. Miwa Shuji, not only him bt his sister was also there, alive. I wish this will help to reduce his anger issues at neighbors. "Head to Seirin Academy, it's safe there!" I said. He leave quickly with his sister. The rain just started pouring down, how unlucky, jumping through buildings will be more slipping. With an unknowingly cooperation with borders the invasion finished in the matter of three hours. Surprisingly, my trion didn't run out and I didn't even get a scratch. I reach over my com s . "Chika..." "Yes, we- we did it right?" she softly reassure. "Yes, we save them, now lets go ho-" I was cut off when I sense someone behind me. I just turn my reygust into a shield and defend myself. "Who are you?" the person who attacked me asked. Quite sarcastic when he is the one who attack me and also the one to ask who I am. But when I look at him I quickly recognize him. Wearing a green fancy goggles,tamakoma's long sleeve, green eyes and a light brown hair with his kogetsu. I just quietly mumble his name...

"Jin-san?"
