Lost Judgment

A massive side-content hub where, while investigating undercover, you revive and probe Seiryo High's various clubs. Each club is its own minigame, and clearing them all is required for 100% completion — the centerpiece and biggest grind of the game.

• Clubs unlock in sequence — progress Dance and Robotics first to meet the stat requirements (e.g. Focus level) that gate the other clubs.
• Each club minigame is independent — clear the ones you're confident in first, and drop the difficulty for the rhythm/combat clubs if those aren't your strength.
• Textbooks and rewards from club progress also feed Yagami's skills and stats, so it's efficient to advance them alongside the main story.

A rhythm minigame where you hit on-screen button prompts in time with the music, chaining combos for a high score. The 100% trophy demands a Full Combo, making it one of the game's hardest activities.

• Input exactly as each note reaches the judgment line — clearing the story is fine on Easy, so save Full Combo attempts until you've memorized the chart.
• Simultaneous (multi-button) and slide notes are the tricky parts — pre-plan your finger placement and keep your eyes on the whole lane.
• The Full Combo trophy can target both the boys' and girls' charts, so grind your Full Combo feel on the easiest song first.

A boxing sparring minigame that plays like a 3D fighter — each face button throws a different punch, and you block high/low and move to whittle down opponents' health, beating a ladder of boxers in turn.

• A stamina gauge stops you from spamming punches — block to ride out the opponent's attacks, then counter into combinations in the openings.
• Watch the opponent's guard height and mix body (low) and head (high) shots to break it down.
• Later opponents (e.g. Wakita) hit harder — don't rush; prioritize dodging and stamina management over trading blows.
• When the opponent's body glows red it's the tell for an uppercut — don't try to block it, dodge and then counter into the opening.

A minigame where you battle other teams in scrimmages using a robot you build and upgrade. As you progress, parts and abilities escalate until you're winning nearly every fight. It's the most involved of the School Stories.

• Keep upgrading your robot with parts won from battles — balancing weapons, armor and mobility gives consistent wins.
• Adjust your build to each opponent's weakness (ranged vs melee); early on, grow your stats before pushing hard.
• Control is real-time, so spacing and attack timing matter — refighting early opponents with a late-game build makes part farming easy.
• You can win on territory when time runs out, but the fastest win is capturing the enemy base — lay blocks to carve the shortest path to their base and seize it.

A motorcycle racing minigame within the biker gang investigation. There are 12 races total, each tougher than the last, decided by cornering and boost management.

• Brake just before corners and cut the inside line to keep your path short — full-throttle cornering leads to crashes.
• Save boost for straights, and use contact/clashes with rival riders to steal positions.
• Later races require memorizing the course — run the hard ones once just to learn the track, then chase the result.
• The boost meter fills slowly on its own, but pops up much faster if you wheelie on straights or drift through curves (lean left/right while inputting) — only ever wheelie on straightaways.

Skate around the city, landing tricks off ramps to score. Each park has a clear goal plus a tougher secondary goal for the TownGo award, and there are skate races too.

• Hit jump in time as you reach the ramp, then mash the button in the air to land the trick — higher combos score far more.
• The TownGo secondary goal needs fast, back-to-back tricks in a short window, so chain combos through ramp-dense areas without dropping them.
• Missing the landing timing breaks the combo — repeating tricks you can reliably land scores more steadily than overreaching.
• Grab every coin between tricks to push the combo to 10x — the game then spawns gold coins worth far more than silver ones; if you're stuck, just ride back and forth between two ramps/pipes to keep the combo alive.

Race a drone you've built through aerial courses, in Single Races and a multi-course Grand Prix. Clearing all leagues and time trials is the completion task.

• Upgrade your drone's speed, acceleration and durability with parts — higher leagues are very hard without investment.
• Passing through rings/gates cleanly builds boost — ease off before corners to hold your line, then dump boost on the straights.
• In time trials every collision costs your record, so nail a safe line first, then sharpen it aggressively.
• Recommended build: within the 250-cost limit, run an S-ONE Adamant Frame (any color) with the MTG Motor, the Low-Cost Turbo, and the S-ONE: S3 Propeller (best speed stat at 25) — almost no course needs durability, so dump everything into speed.

A sugoroku board game where you yourself are the piece. Roll a die to move, resolve each space's event (gift, battle, drone, parkour, lockpicking), and win by reaching the goal first. Beating strong rivals permanently teaches you their skills.

• You choose your direction, so plan your path to step on blue (gift/star-plus) spaces and avoid red (star-minus/battle) ones.
• Yellow-space minigames (drone, parkour, lockpicking) are short action bits — handle them calmly for stars and items.
• Even low courses net hundreds of thousands of yen per run (millions on hard courses), so it's great for money — collecting rival skills makes later runs easier.

A collection of classic SEGA arcade titles in Club SEGA. You can play 1980s–90s arcade hits and Master System games, and playing every arcade game at least once is a completion task.

• Completion only wants you to 'play' each game, so it's about running every cabinet once for the record — not high scores.
• Sonic the Fighters, Fighting Vipers and Virtua Fighter 5 are fighters — a single CPU match each is enough.
• The Master System games in Yagami's office can switch between Western and Japanese versions — check both if they're tracked separately.

Standard Japanese riichi mahjong — the series' biggest wall if you don't know the rules, but learning one winning pattern is enough for completion.

• Keep your hand fully closed (never call Pon/Chi) so you can declare Riichi.
• Chase Tanyao (only simples 2–8); when you're one tile from 4 sets + a pair, declare Riichi and a yaku attaches automatically.
• Completion only needs wins, not big hands — prioritize fast wins over value.

Japanese chess; the key twist vs. Western chess is that captured pieces can be dropped back onto the board.

• Build a castle (gakoi) around your king first — Mino castle is the easiest starter.
• Captured pieces can be dropped anywhere — parachute them deep into enemy territory to apply pressure.
• Completion just needs wins, so a safe formation that limits mistakes beats over-aggressive attacks.

A secret gambling den for hanafuda-based koi-koi and oicho-kabu. You need the door code (7120) to get in.

• Koi-Koi: match same-month cards to build yaku (scoring combos); bank even small yaku immediately for safety.
• When you complete a yaku, choose to call 'Koi-Koi' to keep building or stop — if the opponent looks close to a big yaku, lock your points in.
• Oicho-kabu: the closer your cards' total last digit is to 9, the stronger — gambling cheat items make the completion grind much easier.

A secret casino offering poker and blackjack, accessible by progressing the Casino School Story.

• In blackjack, follow basic strategy — stand on 17+, and only push when the dealer's up-card is weak.
• In poker, concentrate your bets on strong hands rather than over-bluffing; chip rewards feed completion and item exchange.
• Gambling cheat items let you bank big chip totals reliably.

A bar darts minigame with rules like 01, Cricket and Count Up, where aim accuracy and gauge timing decide your score.

• Stop the wobbling reticle on the center (high score), then stop the accuracy gauge in the yellow zone.
• In Cricket you must 'capture' each of 15–20 and the Bull with 3 marks — focus on closing one number at a time.
• Count Up is pure point totals and good for practice — farm easy opponents for the wins toward completion.
