Onikami Legacy Beginner Guide

When you launch the Onikami Legacy, you’ll be at the entrance of Otama Village. There, you need to talk to the NPC at the entrance of the village.

When you do so, he will give you a Quest with the location of the Old Nichirin Katana,  after getting the Katana you will have to compete in the Final Selection. To enter the Final Selection, you’ll need to get level 15.

However, it will likely take multiple days in-game, so you should get some Gourds to improve your breathing level.  

To breathe you need to press “G”,  it is also unlocked at level 10.

To enter the Final Selection, talk to the Final Selection Subscriber and head to the Final Selection. Once you get there, wait until it’s night and talk to the Ubuyashiki Girls to get into the Final Selection.

To pass the final selection, you need to kill 20 demons without getting killed yourself. To know if you have 20 kills just press F to breathe as it is unlocked at 20 kills.

If it opens, it means you have 20 kills. After Final Selection, you’ll be able to get your own Nichirin Katana from the swordsmiths.

If you do not have a Breathing Style, then you need to talk to a Trainer to obtain them. If you have not bought the Gourds, finish them as soon as possible.   

Demon Slayers 

The Demon Slayers are part of the Demon Slayer Corps, their main job is to hunt the demons. One needs to pass the Final Selection to be a part of a Demon Slayer.  

After becoming a demon slayer, you will mainly be doing Quests and killing Bosses to progress through ranks until Max Rank. 

You can get Crow Quests at any level, but Boss Quests start showing up at Level 50+ and you finally get the Slayer Mark at Pseudo-Hashira.

Demons: 

To become a demon, you need to ask a Level 100+ Demon (Futsu+) for blood. You can also born as a demon but it has a low chance

You can become a Demon during your Slayer Progression. The Demon progression will start on getting the Demon Quest at the Small Cave where you will have to grind till you get the Blood Demon Arts.

How To Make Money

Trinkets 

Here is all you need to know how and where to sell trinkets. For this, you need to go to a village and meet this NPC who gives you a delivery quest. 

You need to go and press the green button in front of him. As soon as you press it sells every trinket in your inventory. 

Money Transfer

To pick up and drop money in Onikami Legacy, the first thing you need to do is tap on the money bag icon type the amount and press enter.

To pick up just walk up to the money.

Food

On the UI on your screen, you will see a red bar which is your HP, and next a purple bar which is your breathing bar. Next, we have the food bar.

  • As a demon, you get food from eating the humans.   
  • There are two options of human food The Energy and The Ramen but both cost money. 

Ranks

Once you reach a certain amount of kills you rank up. Each time you rank you get more damage, HP, and speed.

Party

To get the  Party feature in the game you need to open the main menu. To open the main menu just press the menu button found on top of the screen or press M on your keyboard. 

Click on the Party option: You can create your party by tapping on the Create Party option. The other option is to join one by accepting an invitation. 

When you create your party you can tap on the Username option and type in the players username to invite them to your party. 

 The party is quite useful as in a party no one can harm one another. 

Wall Climbing

You can unlock this feature at 20 kills/ranks to do it. Double jump on a wall. 

On a PC it will fling you back however on Mobile it will fling you up. 

You will have to dash up as it flings you back to climb it. 

It will take some practice but is quite useful. 

That completes our guide on the Onikami Legacy.
