世界をおもしろくするのは 
我々 我々 我々 我々 
我々自身だ 
この素晴らしきかなインビテーション 
そこには大人も幼女も関係ない 
またゼロから始まる愛のダンジョン 
カタカタ骨の折れそうな新世界 
あれはなんだろう これはなんだろう　どうのこうの言う前に 
仕方ないだろ やるっきゃないだろ　生き残れ 
状況把握で戦況をうまく切り抜けろ 
とかなんとか言ってる場合じゃないような異常事態 
「俺の名前はナツキ・スバル！　天下不滅の無一文！」
「ターニャ・フォン・デグレチャフ少佐だ」
「私がアインズ・ウール・ゴウンその人だ」
「どうもカズマです。 …え？ ここかっこいい事言うところなの？」
帰りたい 帰るな 
乗っ取りたい 乗っ取れない 
あー 
でも異世界もわりといい世界 
ここは来るもの拒まず千客万来 
案外気の持ちようみたい 
どこにいてもパラダイス 
世界をおもしろくするのは 
我々 我々 我々 我々 
我々自身だ 
Oh 
異世界かるてっと！
異世界かるてっと！
異世界かるてっと！
異世界かるてっと…

What makes the world interesting? 
We, We, We, We, 
We, ourselves do 
This wonderful invitation 
There's no difference between being adults or being little girls. 
Another dungeon of love starting from zero 
A new world that seems to so tough that it may break bones. 
What is that? What is this? Before you complain
It can't be helped, we have to do it, To survive!
Get through the battle by analyzing the situation.
But, it's an unusual situation that you don't even have time for that
"My name is Natsuki Subaru! Sentenced to immortality and I'm also completely broke!"
"Major Tanya von Degrechav is who I am." 
"I am the great Ainz Ooal Gown!" 
"Hi, I'm Kazuma. ...Eh? I'm supposed to sound cool here?" 
I wanna go home 
Don't go home 
I wanna take over 
I can't take over 
Ah---! 
But the different world is a nice world 
Whoever visits is always welcomed 
It depends how you see 
It's a paradise no matter where you are 
What makes the world interesting? 
We, We, We, We, 
We, ourselves do 
Oh- 
Isekai quartet! 
Isekai quartet! 
Isekai quartet! 
Isekai quartet...
