Season 1

Hakuno feels a rage build up inside of him as he lives through the repetitive virtual world of SE.RA.PH, and it fills him with a sense of purpose.

Saber proudly introduces herself and prepares Hakuno for the war ahead. But finding another Master to battle proves to be harder than anticipated.

Hakuno and Saber meet Rin, a self-proclaimed Resistor. Hakuno learns that he must kill Shinji, the Floor Master, in order to ascend to the next level.

After making it to the next level, Hakuno and Saber are immediately ambushed. Just as things seem hopeless, they meet a stranger named Rani VIII.

Rani VIII tells Hakuno about the Floor Master, Dan Blackmore, and they learn why he can never ascend -- no matter how many lives he takes.

After ascending to the mysterious third level, Hakuno meets Alice, a cyber ghost living alone in this haunted wonderland.

The only way out of the time loop they're trapped in is to defeat Alice. Hakuno is hesitant, despite knowing how many she's killed before.

Rin gets them ready for the fifth level, where a Berserker wanders. There’s no floor master, but something perhaps much worse.

A familiar-looking girl also named Hakuno Kishinami appears. Later, Saber tells the male Hakuno that she's ready to take on the Berserker once again.

Now on the sixth floor, Hakuno and Saber are suddenly attacked by a swarm of beings who look just like Rin and Rani.

Hakuno and Saber reach the final floor, where a thousand years ago, a previous incarnation of Hakuno defeated the Master before perishing.

Now back on the lowest floor, it seems as if Hakuno and Saber have to start all over again -- and they're running out of time.

At long last, the final battle begins. Hakuno’s ultimate opponent reveals his identity and the reasons for constructing this war.
