so for this to work you need to complete the first 2 game boards with a snes controller, after that, youll go to the green room and next to ramb youll find kindness luigi
















talk to him for him to tell you "ill join you later bud!"
ramb will also say kindness luigi is very kind

so you need to do all the secret s rank minigames, and get to the eram fight, halfway through it kindness luigi will help you in battle













after the fight, susie wont show up, so with mini kris you have to push kindness luigi so kris catches him, making the Kindness Luigi Key fall from his pocket, you pick it up

so before fighting tenna kindness luigi will show up and say hi, but he wont show up during the actual fight















after the tenna fight, the knight shows up as usual, but this time ralsei gets a heart attack and gets knocked down, so instead, kindness luigi joins you

so in the actual fight kindness luigi has a special act where the knights attack and defense drops by 10000, this makes the fight easier













in chapter 4, kindness luigi can be found in castle town, he'll give you a cool item called the kindness sword

so this is it! if this helped you, leave a like!
bye bye!
