Glorious Nipponese Steel folded 1200 ATK times.
Only one note here so:
“Longyuan’s weapon:
Has a design reminiscent of a Japanese katana, also the blade part emits a golden light”
Note: For the sword connoisseurs, the note uses 日本刀 (nihonto) which covers multiple types of Japanese swords but the long, single-edge curved ones tend to be generalized simply as “katanas” outside of Japan.
