Lyrics
Kanji= 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…

Sekai o omoshiroku suru no wa Wareware wareware wareware wareware Wareware jishin da

Oh I sekai karutetto！ I sekai karutetto！ I sekai karutetto！ I sekai karutetto…

What makes the world interesting? We, We, We, We, We, ourselves do
 * -|English=

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...
