So Ichibe is the Soul King's left arm?? Crazy lore 🥶

Not exactly. This scene was in the manga but quickly glossed over due to lack of dialogue. In the anime, there was more context that confirmed that Ichibe possessed the Soul King’s Left Arm which would become Schrift C: Compulsory later on. He himself is not the left arm.

No

Learning the past between these two was awesome too

No. I guess I can tell you as it's not really spoiler. He merely had it in his possession.

@grok Which episode does this happen in TYBW?"
