After hearing Anamaria further explanation Ryouma regained his calm.
No matter how angry he was, nothing will change.
Thus, listening to all of the stories has become the top priority.
(But still, this world is 「Earth」? And the place I"ve lived previously is 「Rear」world huh? Well, it was the name given by the people who live in this world after all...)
This also a common story that happens in his world.
Although the sun gives light equally to all nation, the nation called as the rising sun is j.a.pan, while the Earth is round, yet the China is being called as Middle Empire.
When you have to name some place represent both sides, It was a natural for a human psychology to list the world in which side they have lived,
Anamaria then continues talking.
"However, physically there"s nothing such as back and front. Such naming conveniently comes out since among all the world exist, including ours, only two have life in it."
"I don"t care which side which! Tell me the reason why I cannot get back!"
Anamaria shrugged her shoulders.
"It"s simple. To summon human from the 「Rear」 world to this world「Earth」, we have to offer Prana to the existing G.o.d in this world 「Earth」 to get authorization to summon them. This is because there"s a barrier around this world to prevent intrusion from the outside; however, there"s also a similar barrier set up on the 「Rear」 world as well."
"Wait a minute? Enough about the barrier stuff. I was summoned to this world is that not it? Won"t it be enough just by asking the G.o.d who had summoned me?"
"No. Whether or not you can enter each world, depends on G.o.ds within each world whether they let you in or not. In other words, to enter the 「Rear」 world after leaving this world 「Earth」, you have to get permission to enter the 「Rear」 world from the G.o.d who manage the barrier of the 「Rear」 world."
Ryouma head converts the explanation that Anamaria gives into something easy to understand.
(So, it"s free to leave? But the problem is the permission to enter... Isn"t that similar to a self-locking door?)
The auto-lock system which common in a hotel.
It"s easy to open the door from the inside, but when the door closes it will automatically lock itself up, and to come inside from the outside, it requires a key.
Replacing the two worlds as hotel rooms, and replacing the s.p.a.ce between s.p.a.ce-time as the hotel pa.s.sage may make it easier.
"In other words, If it"s just pa.s.sing the boundary barrier on this side then it is possible; however, it is not feasible to pa.s.s the boundary barrier on the 「Rear」 world side. As a result for that? You will be drifted within s.p.a.ce-time..."
"I see, so that"s how it is... "
"But, if that is the case, what if we know the G.o.d who manage the barrier on the 「Rear」 world side!?"
Ryouma told Anamaria in reb.u.t.tal, expecting the answer to this argument.
It is not known since when the people of this world 「Earth」 have been summoning that world 「Earthling」, however, certainly it"s something that has been done more than 10 or 20 years.
In other words, there are more than thousands people that have been summoned to this world 「Earth」.
Some of them might try to return to their original 「Earth」 after running away as Ryouma did.
At least, it was a certain thing that Ryouma is not the first person who have tried to return.
*Bang!*
Anamaria throws a book with dull color on the cracked desk.
"This is the record of human from another world who have tried to return. "
The book that Anamaria had offered is as thick as a j.a.panese Dictionary book that is published by Iwanami.
"It"s not difficult to prepare the return home magic rituals. Because you can just change the summoning ritual a little. But there"s nothing I can do if I don"t know the G.o.d which I have to offer the Prana to. "
Ryouma opened the page of the books and offered it to Ryouma.
"The name of G.o.ds that exist in your world are written here. In other words, this is the name of the G.o.d that we tried to use in the ritual and yet have no effect. "
"That means... Unless I know the name of the G.o.d that have not yet being mentioned here..."
"You won"t be able to return to your previous world."
A heartless declaration pierced Ryouma"s chest.
"Tsukiyomi, Susano, Amaterasu, Jehovah, Yahweh..."
Inside the Inn after returning from Mireish, Ryouma shut himself inside his room leaving out Sara and her sister and examined the book desperately.
The face Ryouma shown when returned from Anamaria place is like the face filled with tragedy, which Sara and her sister cannot describe it with words.
In front of the room where Ryouma stayed, the sister was standing.
Their gaze is poured on the door of Ryouma"s room.
"It"s already 5 hours..."
Laura nodded her head toward Sara"s words.
It"s already late night.
"Ryouma-sama..."
The sisters knew how Ryouma"s feeling to be unable to return home.
Shivers run through their body just by imagining what they would do if they are in Ryouma"s position.
However, the sisters are unable to save Ryouma.
What they can do is only feeling concerned about Ryouma condition while standing in front of the door.
