>>3834513It's a lovely idea, but I don't think Mika actually has any of Mikaela's soul, at least not yet, for a number of reasons:
>If Mika had half the soul and Yuu had the other half, Sika would have already won a long time ago, rather than spending the whole manga up until now fighting over Mika with Saito/Guren>When demon Mika in his child form was peering into Yuu's soul, he could go back to the orphanage days just fine, but when he tried to look at a memory with Mikaela's corpse in it, he had to get Eyeball Yuu's permission to enter and was spotted right away by Sika because he wasn't supposed to be there>In the current flashback arc, Mika never bought into the "Angel Mika" line that Yuu was pushing; at one point, he even said Mikaela reminded him more of Yuu>Mika couldn't read the words on Sika's monitor, but Yuu could>Mika was a lot more confused and disoriented than Yuu in generalAll of this points to the Mika from today not having been around in any form back then and not having the personal connection to those past events that someone with Mikaela's soul should have. This doesn't mean he isn't important - he's still the first and only successful vessel to be discovered since Yuu himself, the king of the demons, the flashpoint of every major conflict in the series, etc. He's just slightly less of a fucked-up science experiment than Yuu is.
