Drawing is okay, dialogues are okay, the plot is post hoc only. to rush somewhere into a more dangerous world, but most importantly… Maybe “Apprentice of the strongest demon king, enters school from the parallel world.” ? Kind of reminds me of “in another world with a smartphone” from the cover. Maybe the atmosphere? So we wait.
