After visiting Amane, it says "Main: talk to Hisae to continue the mission" but she says "Not yet, when i do i'll let you know"
That's strange. After returning from Amane's mansion, when you go to Hisae, the mission to go see the spider demons should activate and then you should go to shinobu. Also, that hint you mentioned should appear in the mission where you meet Susamaru... Did you do anything weird in the battle against her?
No, no hice nada extraño, solo fui con Amane antes de la misión que se suponía me tocaría porque estaba desesperada por no poder hacer nada, pero por lo demás nada extraño ni fuera de lo normal, no creo que hubiera podido hacer mucho, o sea es una novela gráfica después de todo,the bug has been from the previous version but I didn't say anything because I thought you would fix it in this update.
Found the bug, if you decide not to continue the fight against Susamaru and instead you get to Amane's mansion when you get back the game will skip from the mission against Kanao, Muu and Zeniko to the mission against Rui's familly which requires that you talk to Shinobu but you cant without getting Kanao.
