User blog comment:Lacusweltfan01/What do you think the history of Lacus is?/@comment-36009152-20190401015906/@comment-36009152-20190409202613

An excellent insight, yes Lacus and Yoichi seem intricately linked. It is worth considering that Lacus is assigned to specifically target humans related to the Seraph of the End, which would explain his actions to Yoichi’s sister and places him in a rather notable role long term particularly with Yoichi being involved with it.

On the plus side it is better they could see that the Horseman were disappearing, rather than being eaten by them :O

Even better news, Lacus and Rene were not just thrown into the story for the sake of it. Other characters can appear as and when, but Lacus has ties with both Mika and Yoichi at least.

You will surely get your hope to see Lacus again!
