From Trigger Magazine #006:

"Up until now, the only friends I had were in my head." I have to say this phrase is pretty powerful and it left me quite speechless. Every episode Mako gets abused pretty badly, but never did I feel bad for her. But this phrase on the other hand really got me. I really felt bad for her.

「私は今まで頭の中にしか友達がいなかった。」と衝撃的な事をあっさり言っちゃうマコちゃん。毎回扱いが酷いマコちゃんですが、今回の一言はかなりパンチが効きましたね・・・流子ちゃんと友達になれて良かったです！皆もお友達は大事にしましょう。
