"Fairness, aimed upward."
Test if you're Justice20 questions · about 3 minCanon facts
The Ball Game's yellow flag names the yellow soul "Justice."
Its linked items, the Empty Gun and Cowboy Hat, are sold by Bratty and Catty in the MTT Resort alley.
Yellow SOUL Mode flips the soul downward and lets it fire shots upward to destroy bullets and bombs — introduced in the Mettaton battles via Alphys' phone upgrade.
In the Photoshop Flowey fight, the yellow soul attacks with gun and bullet-flower patterns.
What it means
Justice is the only soul mode that shoots back. Not wildly — precisely, upward, at the exact projectiles aimed at you. High-Justice people notice imbalance before anyone names it, and they'd rather be unpopular than unfair.
The shadow side is turning every disagreement into a tribunal. The yellow soul's lesson is aim: respond to the harm, not the person, and only as much as the harm.
Answer harm with aim, not volume.
