How To Complete Substory 29

Follow our guide to complete Substory 29: Litterbugged in Like a Dragon: Infinite Wealth. Learn how to invest $3,000, identify trash, and defeat Sojimaru v 2.1.

Alright, let's tackle Substory 29, also known as "Litterbugged," in Like a Dragon: Infinite Wealth. Professor Okita needs your help with his new prototype, Sojimaru. It's going to cost you a bit upfront, but we'll get through it together.

Walkthrough:

1. Invest $3,000 into Professor Okita’s project

   First things first, Professor Okita is going to ask you to invest a hefty $3,000 into his work. I know, that sounds like a lot, especially in the earlier chapters of the game, but don't worry, there are several solid ways to make money quickly:

   • Hawaiian Haunt Dungeon: Once you reach the end of Chapter 5, you can access this randomly generated dungeon. Running through the first floor can net you a few thousand dollars, depending on how many enemies you fight. It's also great for grinding levels and getting weapon upgrade materials. A full clear of all floors usually takes about an hour for players around levels 18-25, but it gets faster as you level up.
   • Sujimon Battles: Unlocking the Sujimon League in Chapter 4 is another fantastic way to earn cash. Battling other trainers and taking on Sujimon Raids will give you a nice boost.
   • Smackdown Opponents: Around level 20-25, you'll start seeing lower-level enemies with blue icons. If you press the correct trigger or key as a fight begins, you can instantly K.O. them and grab the rewards without a full battle. Just running around lower-level areas and doing these can earn you hundreds of dollars in minutes.
   • Collect Items: While not the most lucrative, simply running around Hawaii and collecting items to sell can add up over time.

   Once you've got the $3,000, head back to Professor Okita and invest it. He'll then get to work on upgrading Sojimaru. After this, you'll need to progress the main story a bit or tackle some other side content until the next part of this substory pops up.

2. Identify trash correctly as requested by Okita

   Your next task is to head down to the docks, located just east of Anaconda Harbor Park. Okita needs your help to improve Sojimaru's AI by teaching it what counts as trash. It's pretty straightforward: anything that looks old, tattered, or has holes in it should be identified as trash. Anything else is
