Hi, it’s Junko from Japan. Ryomen Sukuna’s Domain Expansion technique, Malevolent Shrine says FUKUMA MIZUSHI in Japanese. In short, FUKUMA means “demons are lurking” and MIZUSHI is a Buddhism building with double doors. Let me explain what each Kanji symbol mean in detail!
FUKUMA

FUKU = lurk, hide and wait
MA = demon, devil, evil
The origin of the word FUKUMA is FUKUMADEN. The DEN symbol means “palace” or “castle” and FUKUMADEN makes the place where something evil is lurking around.
MIZUSHI

MI = prefix used for showing respect
ZUSHI = a Buddhism double-door shrine or altar
ZUSHI is a Buddhism altaer with double doors. Buddhism tools like statues and ritual implements are enshrined in it. MI is a prefix for the polite way of saying something. It’s used for something valueable or someone superior.
Here’s the actual picture of ZUSHI alter owned as the national treasure of Japan. It looks like the shrine in Sukuna’s Domain Expansion, isn’t it?

In this video, you can see Ryomen Sukuna cast Malevolent Shrine. He says RYOIKI TENKAI FUKUMA MIZUSHI in Japanese.
Mizushi is originally a place for something divine. But Sukuna’s one is a place for demons. It creates an area in which Sukuna’s attack never fails to miss. Fierce slash keeps attacking the opponent until the technique ends.
