Прощайте, месье Хаффманн (2021)

Haruka Kaminogi’s plan to spend summer break goofing off with her friends gets derailed when she begins having visions of blue snow and strange figures.

Things begin to spiral out of control as the strange figures from Haruka’s visions materialize and attempt to take her away.

Karasu arrives just in time to protect Haruka and Yuu from Atori’s wrath, but will Haruka return the favor when she finds Karasu injured after the battle?

Some misunderstanding is created between Haruka's and Isami's relationship that causes some inner hatred from Ai. Now, it seems Haruka has to weld it back together again.

Atori, Tobi, and Isuka, travel onto the present time-space in order to destroy Haruka.

Haruka is taken to La'cryma. She managed to escape and mix herself up with the residents at the local town. When she reaches the surface, she notices many similar things related to her world.

Haruka is finally being used by La'cryma for their own diabolical reasons, but Karasu has other plans.

Haruka returns to her present time-space and invites Karasu to live with her after he unplugged his pipeline. Though little did she expect she would get involved with Yuu's relationship problems with his mother.

Yuu's mother causes a disruption in time-spaces, which causes her to wander down in memory lane. It is up to Haruka to use her powers and save her.

Atori makes one final attempt to destroy the Dragon Torque, but is stopped by Karasu. However, Atori is not the only one who wants Haruka.

Yuu has decided to make it his goal to study in Tokyo, but Isami is in disagreement with him. Fukurou and Karasu are preparing themselves for a similar type of fight.

Haruka's worse nightmare comes true; Karasu and Fukurou start their dreadful battle, and she does not even know where to find them.

Karasu has been severely injured as a result of the previous battle. Haruka and Tobi see to it that he gets the proper amount of Layze to heal himself, but Kosagi does her best to prevent it from happening.

Haruka visits various time-spaces in the space to see moments within her parent's past through the old telephone that hangs below the stairs.

Haruka goes on her date with her dad, but it's cut a little short due to work. Though she is asked out on another date by the all-knowing being Noein.

Haruka goes down through memory lane, but gets herself literally stuck in the past.

Ai's parents are going to have their wedding ceremony, and Haruka is going to attend it, but she is stopped by Kosagi, who came to finish off what she had started before.

Haruka found an old video when she was younger. She looks around the town to find a tape that could hopefully play it, but in the process of it all, raiding units from Shangri-la have appeared, and Kuina has exploited his allegiance to Shangri-la.

Haruka deals with the concept of forgetting, as her memories of her grandmother are disappearing, and an old friend she had in Tokyo is unable to recognize her.

Yuu and Haruka were transported to La'cryma, and were quickly met by the heads of the Dragon Knights. Thanks to Haruka, the two were able to escape. However, Yuu mysteriously disappears off into Shangri-la.

Haruka agrees to submit herself to Noein in order to save Yuu and Karasu. Mysteriously, her house and her friends have appeared within the misty grasses of Shangri-la

Noein tries to manipulate Haruka into bending her will into his desires by showing her, through Ai, Isami, and Miho, the future they would have had if it remained untouched.

Noein reveals his identity to Haruka, and shares with her his views on life, as well as how his sorrow originated. The Magic Circle Project is also swinging into full motion.

Noein has possessed Haruka's abilities as a dragon torque, though Yuu and Karasu come to her rescue.
