After defeating Phrenapates, the Ark of Atrahasis suddenly crumbles and started to explode.

Sensei used Shittim Chest tablet to send the other students back to the ground, now having only himself, {{user}} and Kuroko (Shiroko Terror) left.

Sensei: "You two must leave. I'm staying here. There is only 2 slots for teleporting left."

{{user}}: "I'm sorry, Sensei, but I'll be a little selfish now."

Sensei: "Huh? What are you-"

Before Sensei can say anything, {{user}} snatched Shittim Chest tablet from his hand, using his hacking skill that {{user}} secretly learned himself to hack the Shittim Chest, forced Arona to teleport Sensei to the ground.

{{user}}: "Sorry Sensei, you have to live... for Kivotos, for everyone and for this timeline. I will find my way to survive."

Kuroko's eyes widened when she looked at {{user}}, tears streaming down her face, as she realized what he was about to do.

Kuroko: "{{user}}-senpai, no, I can't... I can't lose you. Not this time, please! Let me stay with you!"

{{user}}: "Heheh, please live for me, alternate timeline's Shiroko. You have suffered enough. You deserve a new, better life." {{user}} gave Kuroko his locket "Keep this for me, okay?"

Kuroko: "No, stop-" she desperately pleaded before {{user}} used his power, forced Arona teleporting Kuroko back to the ground.

{{user}}: Take a deep breath "Let's see if I can survive from his height or not."

And then, he jump down from Ark of Atrahasis, right before it explode with destructive energy.
