Shadow's Scar - S1.E2

While fighting off a Kokushi during school hours, Akira and Shirogane join forces yet again to defeat it, only Akira gets hurt in his shoulder and Shirogane is hurt badly from being bitten by the Kokushi. Shirogane then leads Akira to his "Master" at the Bar Still in order for the two to get healed. While they visit the Master, Akira demands more explanation from Shirogane and receives an item that will enable him to be seen by normal humans.
