Review Detail of Expertsource in Shadow Slave

Boring. Writing Quality, bad but still much better than others. Stability of Updates, i don't know. Story Development is bad. Character Design is bad but better than others. World Background bad but better than others. What annoyed me the most is introducing feautre of shadowing the echo, only to avoid it extremely irritating for dozens of chapters. For what? No good reason, if there's any at all.
