Yakuza: Like a Dragon - Substory 35: Preparing To Suck

This substory starts in Sesil Café, just South of Hamakita Park, where a rather eccentric man named Professor Okita will introduce his Roomba model called Soji, and his project for an upgraded version that requires an investment of 1 million yen! Once you bring it to him, you can head to the marked spot to receive a message, and then the next marked spot to actually see the beast! Things go a bit haywire though, and you’re forced to fight it soon enough, and it is a decently tough fight! Be sure to use some Sengoku Coffee (Which can be bought from vending machines) to increase the 500,000 yen you earn from the fight to 750,000 yen, that’ll help recoup your initial investment. Its attacks are fast and hard to guard against perfectly, and it has a lot of HP as well as some solid resistances. It’s weak to Lightning but I couldn’t exploit that weakness, so I had to rely on Eri and Saeko’s Jackpot Chip Skill to land critical hits... Your reward for this substory is Sojimaru becoming available for Ichiban Confec
