Currency

Ninjaverse runs on three currencies. Here is what each one is and where it's used.

Yen Off-chain

The everyday money

EarnDropped by monsters out in the open world, plus quest and event rewards.

SpendNPC shops, and every craft and upgrade fee.

CapYou can hold at most 1,500,000,000 Yen.

Kin Off-chain

The tradeable coin

GetExchange Kessho with Fairy, or hit a level milestone.

SpendThe Ichiba market, the Naraku Shop, and Soul Seal rites.

CapYou can hold at most 2,000,000,000 Kin.

NMON

NMON On-chain

Ninjaverse Mon — an on-chain smart contract that wraps MON 1:1

GetTalk to Nefra (the money NPC, in any academy — e.g. Akakiba Gakuen) and pick Deposit MON: send MON to your in-game wallet, then exchange whole MON → NMON (1 MON = 1 NMON) and Claim.

SpendTegata membership, a Reijuu egg, global chat, and the Naraku Expedition entry fee.

ExchangeInto Yen only through the three fixed chests below — there is no free conversion.

Moving between them — the only two conversions

NMON → Yen — three fixed chests

There is no free exchange rate. Ivanos sells three chests; opening one pays out a fixed amount of Yen. The bigger the chest, the better the rate — buying in bulk is rewarded.

Chest	Pays out	Yen per NMON
100 NMON	100,000	1,000
1,000 NMON	1,100,000	1,100
10,000 NMON	12,000,000	1,200

A chest will not open if the payout would push you over the 1.5B Yen cap.

Kessho → Kin

Talk to Fairy and pick Exchange Kessho. The rate is simply the stone's level:

Kessho Lv 1 → 1 Kin · Lv 5 → 5 Kin · … · Lv 10 → 10 Kin

This is the main way Kin enters the game — the Kessho you don't spend on upgrades become spending money.

What NMON buys

Tegata — the membership pass

Bought from the shop with NMON. An active Tegata is what lets you trade, sell on the Ichiba market, and raises your daily Irai board activity cap.

Pass	NMON	Lasts
Tsuki	500	30 days
Mitsuki	1,200	90 days
Toshi	3,600	365 days

Buying again while one is active extends it — the new time is added to what you have left.

Other prices worth knowing

Thing	Costs
Global chat message	5 NMON
Reijuu egg	399 NMON
Naraku Shop (Fairy)	Kin

Hitting a level milestone (Lv 10, 20, 30 …) pays Kin equal to that level — 10 Kin at Lv 10, 20 Kin at Lv 20 — plus a star gem, and a reset permit at Lv 10 and Lv 20.

Upgrade and craft costs are explained on the Drops page.
