Grisaia no Kajitsu (Visual Novel) Edit
Common Route Edit
Yumiko's Route Edit
Sachi's Route Edit
Michiaki does not make an appearance during Sachi's Route. However it was briefly mentioned that, through some means, Yuuji was able to obtain the permission to demolish Mihama Academy's main building as part of a renovation and reconstruction plan of the school building. This is done as a set up to break Sachi out of her "obedient maid" character.
During Yuuji's conversation with JB, it is revealed why Sakaki agreed to the demolition of Mihama Academy. Sakaki's construction corporation, the East Beach Group, had been colluding with a rival construction group, Nishizono Construction to inflate the cost of building construction illegally. JB and Ichigaya used this incriminating information to force Sakaki to comply with the demolition of Mihama Academy.
