Thoughts

The crystal embedded in the handle of the katana, or at least it seemed embedded, had a familiar appearance to Malachi.

He regarded it as a crystal rather than a crystal heart because it looked nothing like a crystal heart and wouldn't have been able to fit like one.

The crystal in the katana had a much brighter radiance than the exhausted ones in Malachi's car's glove compartment.

Malachi did a rough estimate and saw the crystal in the katana emitted a brilliant radiance just like the crystal heart of the monster dog in the forest.

Malachi wondered if the dried-up crystal heart was supposed to be incapable of recovering the mysterious red gas, of which he still had no idea of its origin or source.

At least, the exhausted crystals he had, even the ones from the previous day, hadn't shown the slightest sign of recovering or regenerating what they had before.

Puzzled by what lay in front of him, Malachi was just as curious.
