Hello Jun. I asked for a permission to rename new page that I did.
The page name is Tarachi, but the real name was Tarachio, which I misread the utaite's name. One of the major problem is I accidentally did the new page under name Tarachio too, but then how reckless and careless am I, there's a 'Rename' button. I hope that you can delete those Tarachio page (the blank page, not mistake with Tarachi that I mispelled the name. Haha) asap.
