On the moment Leona passes through the portal.

Her body was surrounded by light that flowed out from the Dimensional Portal. While surrounded by the portal's light, she felt a constant change in the time. In just moment she felt time going so slow as seconds felt like hours, minutes felt like days and hours felt like its months. In just moment suddenly time moves insanely quick as she felt her whole body turning into the dust.

While resisting the chaotic time Leona has begun to feel an urge for flesh and blood of living being. It was a sign of cursed blood flowing through her veins. In a nightmare world, she and her comrades fought against many foes like a dragon that corrupted by the monster to unseen enemies like plague and diseases.

Cursed blood was one of those diseases spread by twisted creatures looks like a mix of human and bug, but it was more of a curse than a disease because it can't be cured by any means. At the first stage, the victim who infected by cursed blood would first start to carve for flesh and blood of living being then more the victim eats the flesh and drinks blood he or she will slowly transform into the abomination that infected them in the first place.

Feeling madness in her veins Leona tried to her best to resist the carve, but this time the carve too much for her weakened mind from a previous battle. Just like a hungry beast, her bright red eye began to search the flesh to sate her carving.

A moment's later her eye lands on dog leash in her right arm following the leash she found delicious looking food tied at the end.

*Gulp*

Swallowing her saliva in hunger, Leona reached her claw towards the Zipp. With pricked ears, Zipp watched her master for a moment then waged its tail and snorted happily without even knowing its incoming death.

"LEONA STOP!"

Barely able to hold onto her consciousness Leona stopped her hard right before reaching Zipp's head before the blood takes over her mind again she immediately opened her mouth and took a bite from her own right arm.

It was better to eat herself than killing her last companion with her own hands.

In a usual another day in head-quarters of hero association.

"Aaah..so boring. Is there even any returner's left ?"

Fighting against his boredom, Aid Walker stretched out his arms on his chair.' The Returners' was given a name for people who returned to earth after getting summoned to another world. As the ordinary staff of Hero association, his job is to receive and help 'The Returners'.

*Brr. Brr*

Hearing his phone, he slowly reached his hand towards his pocket and answered lazily

"Helloo.."

"WHAT!?"

A few moments Walker's coworkers hear a loud scream and saw him sprinting out of his room like lightning bolt after slamming his door open. Walker received the news about the sudden portal with blue light opened in D City. He knew that blue portal sign of 'The Returners'.

Immediately he arrived at the helipad of the association and saw a beautiful woman with golden hair waiting for him in an already prepared helicopter.

Walker knew who this woman was. Her name is Rose, a human girl who returned with 'The Returner'. She is adopted daughter of Reignhearth the one of strongest returner of the Hero Association, one of youngest returner who received B rank.

The author's tale has been misappropriated; report any instances of this story on Amazon.

Today she will accompany Walker for receiving new returners.

In just a few hours Walker and Rose, arrived place portal has opened. The local police already placed the protection fences and maintaining the crowd of people who arrived at the scene.

After finished preparing the pieces of equipment Walked quietly waited for the 'The Returners' passing through the portal.

A moments later a human hand slowly appears from the portal and a teenage boy around the 16 to 17 age dressed simple blue high school uniform along with a sword with golden handle followed by three beautiful girls.

Each girl was beautiful as in their own way. A first girl is dressed in elegant looking white plate armour, blonde hair dancing in the wind. She looked elegant and charming.

The second girl is dressed in a red top and full-length skirt, with her revealing clothes and dark skin she aroused every male with her every movement. She looked gorgeous.

The last girl is dressed in a light blue robe, short blue hair tied in a ponytail. A face that looking around with curiosity and fear. Innocent and pure.

"It is a F*cking harem!"

Every male quietly cursed while praying for god the male for drop dead from playing too much.

"Typical 'Returner' that received cheat and harem froth another world. Looks like we don't need a force."

The real reason why association sends the high ranking returner with an agent is to prevent a possible scenario that new "Returner" went berserk or using newly acquire power from world to exact revenge or killing people or even try to take over the earth.

With Rose, Walker walked towards the group holding list of summoned people.

"So this is Sir. Kage's world. Nice place."

"Now let's go to the stores you told me."

"Why there are so many people around us ?"

Arriving in front of a group with Rose, Walker heard they in mid of their conversation so he decided to stop it before it is too late.

"Welcome to your home hero. I am Aid Walker, a person who sent by Hero Association to help you and this is my partner Reinghearth Rose."

Finally noticing the Walker, the group stopped their conversation and greeted with Walker.

"Hello Aid Walker, my name is Aoi Kage, and they are my wife's Clare, Amey and Charlotte."

Immediately, Walker opened the list and found a male's name.

"As noted in the list you have summoned into another world two years ago in front of people in a subway station ?"

A little bit surprised at man knowing how he disappeared, Kage replied.

"Yes, I summoned to another world while on my way to my home. Then I..."

Suddenly everyone felt like chill throughout their body, unconsciously trembling. Basked within ocean like killing intent all people simultaneously looked towards tall black figure appearing on the portal.

"What is that!"

"Is that person ?"

"There is no way this thing is human."

From portal haggard-looking large dog followed by a tall armoured person armed with a large claymore. But people didn't fear of a person because of thing it's wearing but because how it looked right now.

With bright red eye shining under the hood person now ripping and tearing flesh from its own right arm that showing bright white bone behind its flesh and eating with delight. It was a horrific and gruesome sight.
