Silk Thread

Use the corrected Silk Thread counts

The creator briefly says 500 Thread in narration, then corrects it to 300. The visible V2 panels support 300. Do not copy the earlier spoken figure into a shopping list.

Avoid counting the same upgrade twice

Silk Thread and Metal Scrap have different required counts. The two-step Flame route needs 1,300 Thread but 1,500 Scrap.

1. If you own the Volcanic Katana already, use the Nightfall line of 1,000 Thread.
2. If starting from Flame Katana, add 300 for Volcanic and 1,000 for Nightfall, for 1,300 before subtracting inventory.
3. If targeting Tornadic instead, start with its 300 Thread and Wind Katana; do not assume it qualifies for the observed Nightfall route.
4. Inspect the selected forge menu again before spending because each weapon has a separate base slot.

Get Silk Thread from Ginzo or boss loot

Mizurri's gameplay shows Ginzo's stock menu listing Silk Thread. Talk to Ginzo, choose Show me your stock, select Silk Thread and inspect the purchase total before confirming. Shop prices shown in one recording may change.

The creator says the two ordinary forge materials can drop from random bosses and considers farming bosses more efficient than shopping. This does not identify a guaranteed boss, a drop chance or a fixed yield; test your own runs before planning a precise farm time.
