MC's narration / thoughts
MC - Suddenly, my voice came.
??? - Why is a girl in this sacred space?
??? - I am not sure... could she be a Miko1?
??? - It can't be. There is no such thing as a girl who is allowed to enter--!
??? - Hey, they're stirring!
MC - After that, I heard a lot of footsteps to the left and right of me. I slowly opened my eyes...
??? - Master! And everyone too...!!
MC - Huh2? I've heard that somewhere...
Mouri Motonari - I heard that some girl appeared... where, where---
Mouri Motonari - Oh, maybe this girl...
??? - Master3, do you know this girl?
Mouri Motonari - No... that's not the case, but anyway, I cannot leave her alone.
Mouri Motonari - Get up. I'd catch a cold if I sleep in such a place.
MC - Well...
MC - I wake from blurred consciousness. Blinking and raising my face, a man with a well-balanced face jumps into my sight.
MC - Even with the influence the setting sun has put upon me, I cannot shake the feeling that I have left my world...
MC - What a beautiful person...
MC - But then I noticed that horns were growing from his head.
MC - Huh... what is on your head...?
MC - If you look closely, everyone here has horns on their head...
MC - A momentary insecurity caught me, the wind blew and I sneezed a little.
Mouri Motonari - Oh, it's a bit cold, please wear this.
MC - Oh... thank you so much.
MC - When I tried to give him my thanks my stomach grumbled.
MC - Ah... excuse me.
??? - Are you hungry? I'll give you this! It's delicious!
MC - Fried dough cake4...? Thank you!
??? - How long have you been here?
MC - I do not know... Suddenly I heard a voice, I noticed it suddenly (?)
??? - Then here...? I do not remember what happened. That seems implausible.
??? - Brother! There are many implausible elements to the current story.
Mouri Motonari - Calm down, Motoharu.
Kikkawa Motoharu - But Master, is is incredibly stupid to say such things!
MC - I am...!
??? - Ah... It's strange, but if it's said like that...
??? - Well, well, I guess you haven't lost your memory. Will you ask for lodging tonight?
MC - Eh?! As if I'd do that!
Mouri Motonari - Now now, there's no need for that.
MC - The man called "Master" turned around and opened his mouth.
Mouri Motonari - I will keep this child5.
MC - Eh?
Mouri Motonari - What about Takamoto and Teramoto?
Mouri Takamoto - It's fine with me.
Mouri Terumoto - We'll be living with her at the castle of Mouri? Yay!
MC - Mouri...?
Kikkawa Motoharu - However, it is too dangerous to bring a girl who is not a citizen into the castle!
??? - But you cannot afford to disobey the instructions of a former warlord...
Kikkawa Motoharu - Takakage, but-
Kobayakawa Takakage - If it gets to it, I will kill this girl when she rebels against Mouri...
MC - Kill? What?!
Mouri Motonari - It's okay, this girl won't harm us.
MC - Then, Mr Motonari6 gently took my hand and lead me to his castle.
/ Scene change - Mouri Castle /
Mouri Motonari - For the time being, do not worry about anything, please take the day off. I will bring clothes and food to you, but if you need anything else please do not hesitate to ask.
MC - Okay, thank you very much.
MC - Mr Motonari left me alone. Looking around the room, it seems to be the kind of thing you'd see in historical dramas...
MC - I followed as I was told to, but... I wonder what I should do in the future...
MC - By the way, that beautiful man seemed nice. Besides, there were words I had heard somewhere before... "Motonari" and "Mouri"...
MC - Huh? Mr Mouri Motonari... no way!
MC - Perhaps I'm in the Sengoku7 period?
MC - Either way, something white and round has rolled into the room... I think I need to leave right away.
MC - If you look closely it seems to be a raccoon8...
??? - Ah, finally found...!
MC - The raccoon is talking... and crying?!
??? - Ah... I'm sorry... I've been looking for you forever...!
MC - According to the raccoon, who gave his name as Imari, this is a different world which closely resembles the Sengoku era of the world where I was.
MC - Imari said that he served a woman named Princess Himeko who ruled this world until recently...
MC - Suddenly, she disappeared, saying to look for a girl who came from a different world...
Imari - I have been searching for "the girl who came from another world" since then, depending on Princess Himeko's words.
Imari - Then you are right here, but since the devil has surrounded you, so you cannot just call me...
MC - Demons... perhaps Mr Motonari's attendants?
Imari - Correct.
MC - So, there are horns on the heads of the attendants... this isn't the Sengoku era I know...
Imari - So please, let's look for Princess Himeko together!
MC - I understand. When it comes to princesses, I may know something. I will help you and this world.
Imari - Thank you! Thank you! Let's do our best together!
MC - Imari was laughing carelessly.
