Majin Tantei Nougami Neuro s01e18
Titre original : Key
It turns out before Neuro crashed, he threw Yako safely above the bridge. Neuro is surrounded by electronically-controlled people. He battles them off until Higuchi activities speakers to emit sound to power up the controlled humans. Higuchi explains why he wants the world to be full of criminals. Yako realizes he's not completely controled by the drug and takes the iPod that controls the speakers to disable them. Neuro uses a 7 tool of the demon emperor Evil Aqua to defeat all the humans. Neuro tries to get to HAL this time only to find him protected by a password. Neuro collapses from exhaustion and Yako must find the password. Meanwhile HAL takes over an aircraft carrier and orders supercomputers to be brought on. The final Sphinx has evolved... and Yako has an idea of what the password is.
