My Countless Worlds ~Enchanted Cape~

After being homeschooled for a few years, Luka leaves the confines of his family mansion for the first time to attend an ordinary school. There he immediately gets an offer to join a goofy drama club and help one of its members, by the name of Alice, stage a play based on her script.

The fame-seeking girl draws ideas from a manuscript called "My Countless Worlds", which she had stumbled upon during one of her visits to the library. However, something hardly inspiring for an artist is hidden among the magical worlds. The last page contains a grim prophecy – in three years' time, on a hot day in July, Alice will die after falling from the viewing platform at the top of Enchanted Cape.

This is the first time Luka has seen the said manuscript, but after reading through it he can't help but notice how eerily similar the author's handwriting is to his own.
