Yuuya, Yui and Cryska are parallels of the same type of people, however with different nationalities who need to learn to connect with others despite their differences, whether ethnic, personal or moral. Not just let go of the identities imposed on them and start living as human beings with their own individualities, but understand that it is possible for humans to connect and work together despite everything. Instead of pushing our ideas on others, learn and be considerate of others so that in this conflict of ideas we find a path that leads us to mutual understanding. The purpose of TE is to demonstrate that despite all our differences, human beings can work together despite all obstacles.

After having to deal with the production and writing of TDA after Alternative, I am immensely grateful to see Yoshimune back on the series as a writer and dedicating a lot of time to production, direction, etc. Its amazing. Look, MLA is WAY better than TE, especially cuz it continues to be Yoshimune's life's work, so some may find it strange that I give the same score to both. But I have to follow my heart , this VN is spectacular and even though the level of emotion isn't the same as MLA, it still manages to play with your heart.
In general MLA > TE > TDA = Extra/Unlimited
