Ep. 21: Renaissance Pembentukan Gambar: Phoenix Kembali ke Masa Lalu
Tayang pada 13 September 2018

With help from Amadeus Kurisu, Rintaro begins a gruelling journey to return to the past by performing consecutive time leaps. After reaching 2025, the day where he is supposed to be captured, Rintaro receives help from Amadeus and the others to evade capture and reach Akiba, allowing him to make the complete journey to 2011. Reawakening his old mad scientist persona, Rintaro has everyone else recover Amadeus' data while he gets help from Tennouji to retrieve Kagari, allowing him and Moeka to stop Leskinen and help send Mayuri and Suzuha safely into the past. However, the attack helicopters show up earlier than usual, launching another missile at the time machine as it activates. (Source: Wikipedia)
