AN:So here is a new story hope you like it ^_^

Jin's POV

Flashback

I was there. I was watching them get killed. I saw him, the killer smirked at me. As he smirks I feel my blood boil with anger but as I reach out to punch him, he was already gone. I just saw them lying on the ground with blood all around them. As a tear came out my eyes and I scream, I felt it, the feeling to want to have revenge. And that is how I became a cold-blooded assassin.

Present

'I was walking down this forest for a long time already, where is the hideout of Nee-chan?' Jin thought as he still walks down the forest but became alarmed when he stepped on a wire.

'A wire? Must be an alarming device for them' Jin thought as he waited for the group to come.

'They need to be faster than this or they won't protect my Nee-chan' Jin thought as he wears his hood. And as he heard gust of winds and footsteps he drew out his sword the imperial arm 'Sakurako' also known as Wave sword: Sakurako. The sword, whenever used by its user generates wave as the user swings it, and according to the user's strength of swinging, the wave will have its equal strength.

And as Lubbock stopped her movement, by tangling her right foot, as Bulat and Tatsumi attacks her at the same time.

"Not bad, not bad" Jin said as he smirked. The group was surprised by the voice because they can't tell if it's a man or a woman.

"But that's not enough!" Jin shouted as he vanished and again they were surprised.

'Where is he or she?' Leone thought as she was looking around trying to find the trespasser.

'Damn I can't shoot him if he is nowhere to be found!' Mine thought as she too is trying to find him but she was shocked to hear gusts of winds behind her and as quickly as she could she pointed her imperial arm 'Pumpkin' behind her but found nothing.

'What the!? Where is he!?' Mine thought alarmed.

'Hmph! They need to be more alarmed than this' Jin thought as he watched the members of night raid trying to find him.

'But It may be fun to play with them' Jin smirked as he ran past Mine and attacked Bulat. But Bulat defended against her sword.

'Not bad big man but let's see if you can withstand this!' Jin thought as he jumped and swinged his sword

'The 'Sakurako'!? The one used by the assassin!?' Bulat thought as he tried to block the wave but failed.

'Heh! That's what you get when you try to block one of my attacks' Jin thought as Bulat lied on the ground his arms hurting for trying to block the wave

'Why is the assassin here!?' Bulat thought as he watched the assassin smirk. But the smirk vanished when Leone launched at him and started to attack him

'Heh! Think your clever enough?' Leone thought as she began to attack Jin. Jin just blocked her attacks with his sword

'Woah! It's Leone-san but still not enough!' Jin thought as he once again swung his sword. This time the one who blocked was Akame with the help of Leone, Lubbock, Sheele, and Tatsumi they successfully blocked the wave.

'Good one but that's not my full strength!' Jin thought as he smirked again. And this time swung the 'Sakurako' harder and with more strength.

"Take that!" Jin shouted and the shout was heard by Najenda and she recognized the voice.

'That voice! It's Jin!' Najenda thought as she started to run where Lubbock said he detected an enemy.

'Don't tell me she's fighting them!? They're still not strong enough for her! She might even injure them!' Najenda thought as she ran faster to the location.

There as Jin is panting the only one standing or let's say can fight is Mine.

"E-everyone! Why?" 'It's only one person but we can't defeat him. Is this how weak we are?' Mine thought as she looked at everyone lying on the ground, Bulat glaring at him, and others devastated. Mine was alarmed when he smirked at her.

'He's looking this way!' Mine thought as she through her imperial arm. Her hand is shaking sign that she's scared of the person in front of her.

'Please, Don't' Mine just thought and closed her eyes because she saw him raised his hand because she knows what's going to come to her.

But then opened her eyes when heard a loud bang, apparently Najenda, their leader just hitted on the head the assassin that tried to kill her.

"Ouch! That hurts, Onee-chan" Jin said as he rubs the part of his head that was hit by Najenda.

'Onee-chan!?' Everyone thougt except Leone

'Oh! It's Jin' Leone thought

"What the heck are you doing!?" Najenda shouted at Jin.

"Ouch my ears" Jin said again and started to pull down his hood showing his face emotionless.

"Nothing, I'm just testing them that's all" Jin explained as he puts his sword away.

"Why YOU of all people is testing my comrades!?" Najenda shouted at Jin.

"Okay fine, I'm sorry" Jin said.
