In Lost Judgment, the Todoroki Boxing Gym school story will unlock after you reach Focus Lv. 2, which occurs during the Seiryo High Robotics Club school story. After you speak with Amasawa in the Mystery Research Club (MRC) room, make your way to the Todoroki Boxing Gym on Sakura River St. When the cutscene concludes, speak with Todoroki then taunt him. A tutorial battle will then ensue! When you don’t die and time runs out, the battle will conclude. Speak with Todoroki when you’re ready to battle Iwashita. After you win, your Focus and Guts will increase!
Speak with Todoroki when you’re ready to battle Kenya. When boxing with him, just don’t die. You don’t have to knock him out 100% of the way just do what you can until the time runs out. During Round 3, he’ll do some pretty nasty punches. You’ll know that they are coming when he gets a white aura around him. Make sure to dodge these! After time runs out, a cutscene will trigger. When it concludes, exhaust all the dialog options with Todoroki then spar with the other 2 members in the gym that are available. Kenya will then leave and you’ll need to tail him. Once you’ve reached the open area near Survive Bar, you’ll need to help Kenya defeat the street thugs to earn more Guts points.
Return to Todoroki Boxing Gym to receive a Boxing for Beginners (Ages 15 and Under). Amasawa will call you with more information regarding the Payback Boxer. After she hangs up, head inside the gym and speak with Todoroki to spar against the 2 opponents you have yet to defeat. Afterwards, you’ll need to talk with Todoroki when you’re ready for the showdown with Onidake. Defeat him!
Next, speak with Onidake outside of the gym to get drinks with him. Exhaust all dialog options then return to the gym for a scene with Mikimoto. Speak with Todoroki then spar with Shingo Ninomiya. Exit the building to receive a call from Amasawa. Head on over to the MRC then make your way back to the gym to ask Todoroki about Genbukai. Since he’s not forthcoming, spar with the 3 new contenders. This will cause a cutscene with Sakuma whom you will then need to defeat in the showdown. When you do, exit the gym and head to Bar Rodriguez in the Bar District to grab drinks with Sakuma. Exhaust all the dialog options. You’ll now be at 50% completion of this story! Before you can continue any further, you must progress in the story. We were able to continue in Chapter 9.
When you’re able, begin a practice match against one of the two players you haven’t fought yet to trigger a cutscene. Afterwards, spar against the other opponent to trigger another cutscene. When it concludes, make your way over to Smile Burger (Food Truck) near MIRAI Batting Center. Once you approach the food truck, a cutscene will trigger then speak with Oshikiri.
Return to the gym then speak with Todoroki to begin the showdown. Defeat Wakita then speak with Todoroki to begin sparring with the next opponent. After you win, exit the gym and exhaust all the dialog options. Next, reenter the gym to trigger a cutscene then begin the showdown against Mikimoto. Win then make your way to Bar Rodriguez in the Bar District to speak with Todoroki. After you exhaust all the dialog options, make your way back to the gym.
As you approach the gym, you’ll receive a call from Amasawa. When it concludes, enter the gym and begin a sparring match with Kazuki Himekawa. Once you win, begin a showdown with Yum Woon Sen. Next, make your way to the MRC to hear what Amasawa has to say. Exhaust all the dialog options then return to the gym for yet another showdown. Defeat Chizuru the Lancer. After you win, you’ll have to leave the gym then reenter it to trigger a cutscene where you’ll learn who your last opponent is before going up against Kenya. Speak with Todoroki when you’re ready to begin the showdown.
After you defeat him, leave the gym to receive a call from Amasawa. She’ll want you to meet her at the MRC again so head on over to the school. When you’re ready, speak with Amasawa to kick off your plans. You’ll need to equip a disguise so go ahead and do that! After the cutscene, return to the gym to face off against Kenya. You’ll have 3 battles with him back to back so be sure to win each one. I found his middle form to be the most difficult to deal with and had to go the full 5 rounds with him in order to win. Once you completely defeat him, a cutscene will bring you outside where you’ll have to defeat the gang. When you do, a cutscene will trigger followed by another fight. Once again, defeat the opponents to complete the school story.
