Easy money
Join the Kurou family. Get about 50 yen fighting the man when you join the "family." You will get about 50 yen more for baby-sitting the kid. The night that Dona Dona goes to get the money from the residence, go to the girl, Suzu. "Rescue" Dona Dona. When you say you are on his side, he will call you a fool or something similar and fight you. Bring the safe with you to Suzu. When she sees that Dona Dona is not there, she will walk away. You can now get the 180 yen that was in the safe.

Easy Points
Progress into the game and do the best you can, preferably under the hard difficulty setting. Once you make some progress, go to the train place and leave the pass. That is the easiest way to get points, and has the least cost in time. With it being in hard mode, if you get a good ranking you get a lot of points.

Easy kills
On the first part of the game on day 1, skip the bridge and go directly to the foundry. A man will talk about it. Attack him. You will then fight 100 men. You can do this as often as needed. This will help your money and your weapon.

Dona Dona's home
At the beginning after you fight the man on the bridge, go underneath it. Look in the shack and see who is in there. Talk to him, say something like "What are you doing?". He will say "This is my home."

Stealing from the girl
If you befriend with the girl, you can steal her items. Just throw them out the door then move them as desired.

Funny father expressions
After you chase the man with the afro and the girl in the "Quick game completion" trick, walk behind the wall and talk to her dad.

Quick game completion
Use the following steps to complete the game in about one hour. At the start of the game, you normally fight the man. After the fight, tell him "Ok...". He will ask if you want to join his clan. Answer "Not interested...". After that, take out your sword to frighten the girl. She will get scared. Say to her "Give me all your money..." or something like that. She will run off.

Next, go to her house. Her father will say that she has not come home yet. Leave and return to where you were before (the bridge). Then, go back to her house again. She will be there with a man with a afro. Have your sword drawn, and she will stay scared. The man will tell you to put it away. Attack him, and after the fight, he will flee. The girl will go with him. Return to the bridge again. Once there you will fight and will kill him. After that, return to where the girl's house is located. You see her father getting tortured.

You have two choices that can be done here. Choose to fight the man that is kicking the old man. After that, kill the man with the gun. Return to the bridge then go back to the house. Walk in with your sword. The girl will run off again.

After that, join any clan and you will finish the game. Because you are not friends with the girl, you will eliminate a large part of the game. You will complete the game and unlock another costume.
