Daichi Hayashi has been many things: husband, father, protector, government worker.

But there is another part of his life Riku has never known.

Behind closed doors, hidden files, and classified reports, Daichi works within P.A.T.H. — an organization built to monitor, contain, and suppress incidents connected to the spaces between worlds.

Riku’s disappearance was not normal.

Sara’s arrival was not random.

And now, the impossible thing Daichi has spent years investigating has entered his own home.

As P.A.T.H. turns its attention toward Riku and Sara, Daichi realizes that protecting his family may mean standing between them and the very system he serves.

Sara Redmere has crossed worlds, survived the mall, and claimed a sword that should not exist in modern Japan.

Now she has to learn house rules.

After the gray car appears and the danger around Riku’s return becomes harder to ignore, Daichi Hayashi begins setting boundaries for the apartment, the family, and the girl from another world now living under his roof. Phones stay charged. Locations stay visible. No one leaves alone. Weapons stay hidden. Exits matter. The next thirty seconds matter more.

But Sara is not used to rules that feel like leashes.

And when she practices with Torrent, Daichi begins to understand just how dangerous the Scarlet Blade truly is.

In this world, survival is not only about strength.

It is about control.

Sara Redmere has survived monsters, roads, bandits, and another world.

Now she must survive the mall.

After a morning of police statements, school paperwork, and too many people staring, Daichi decides Riku and Sara have had enough official pressure for one day. Sara needs clothes, supplies, food, and a better understanding of modern Japan.

But a simple shopping trip becomes something far more complicated when Sara reveals the money she carried from Valenmere: five gold coins from a civilization that does not exist in this world.

To Sara, it is just coin.

To Daichi, it is evidence.

And when Sara finds a handmade sword that no one else can properly wield, the modern world begins to realize that the Scarlet Blade did not leave all of her danger behind.
