A Slytherin who traveled through time and wanted to live a low-key life but was repeatedly persecuted and was finally forced to leave the magical world; an orphan whose parents were members of the Order of the Phoenix and did not receive the care they deserved after their parents died; a liar who still has some conscience; a demon king who was forced to accompany the three fools in front of him and traveled back in time...
When the Dark Lord really disappears from the magical world, when the magical liar moves to the non-magical world, when the orphan of the Order of the Phoenix joins forces with a Slytherin to deal with Dumbledore, I wonder if anything interesting will happen...
