Dunno what to think about this.
In 1st place, Nagi was based for telling Yuko to just fucking die. If she did this to basically make the fucking mom to stop pestering Reiji, then it's the biggest display of care someone did for him.
But in 2nd place... i'm scared. Yuko saw Reiji and made a happy gesture. Maybe ahe knows she'll die knowing her son will continue the cycle of misery. Considering what Ryou put into her release summary (when those 2 who carry Thanatos' soul within themselves clash, a new door to the abyss opens) and considering Reiji dragged Yuri into his abyss of misery, could say the root of the issue wasn't solved at all. Nagi's solution may be quite superficial, and she cucked Reiji from talking his heart with his mom.
Maaaaan don't know what to think. This decided Nagi is too unpredictable.
Maybe Reiji will get pissed at Nagi for not letting him make a clean break with his mom and she ends going to Tokyo to do JAVs, disgusted, disappointed and pissed at Reiji for being too much of a mommy boy 'till the end and push Reiji deeper, causing him to cling into Yuri and even accept to go to Hiroshima with Kazumasa's family before Ishibashi comes into his house, because now she despises both Kuroses for both being demons and spineless sissies unable to make decisions on their own.
Or maybe (cross your fingers this ends being the case) Nagi decides to stick with Reiji and head towards a collision route against both Yuri and Ishibashi. Reiji trying to reason with his former teacher and now "fiancé" will be his next and final test to see if he still can be a person of his own.
Future is quite uncertain, and Esemori still doesn't die. It seems like he has a last thing he wants to do. Either Yuko is brought to Tokyo if some arrangements are done (it means Yuko's hermano will be needed for this) or Shino'oka brings Esemori to The Town.
Anyways, even if it's gonna be in vain, hope Yuko finally lets Reiji go, both physically and mentally.
