If there are any games on GCCX that give Arino a 50/50 chance, it’s anything with ninjas. Ninja Gaiden tortured him, but he beat it; he couldn’t finish Mystical Ninja, though (spoiler: he did in the DVD Box), and though it’s only remotely related, Genpei Touma Den gave him a rough time. And now, Arino faces the PC Engine classic Saigo no Nindo (Ninja Spirit), the Irem action game that’s slower-paced than Ninja Gaiden, but still challenging.
