Review Detail of Solo_BiriBiriBiri in Otaku's journey through the multiverse

Author-san, keep it up! Although I have some issues with this novel, just keep writing! Also, I think starting a new fanfiction would be a good idea in the future. Though, I recommend you to read more novel before starting a new one so you could do better. Analyze their writing styles, dialogues and character designs. Also, use grammarly.
