Another possibility is that the stray devil has some connection to an ancient power or prophecy in both universes. In Naruto, there are many prophecies and ancient powers like the Sage of Six Paths' power. In Highschool DxD, there are also powerful artifacts and prophecies. The stray devil could be linked to these, and its presence could be the key to unlocking some hidden secrets or powers that the characters need to face a greater threat in the future.
The stray devil could be a plot device to bring out new character developments. For example, in Naruto's world, the characters are used to dealing with their own types of threats like the Akatsuki. But a stray devil has different powers and motives. Similarly, in Highschool DxD, the devils, angels, and fallen angels have their own power dynamics. The stray devil's appearance could force characters from both sides to re - evaluate their alliances and strategies.
