The ending makes exactly 0 sense, the authors conveniently forgets past actions to cause spur of the moment 'speeches' that are destroyed by past events. Example being: Hecate talks about how she came to this world and learned about emotion and how she understood it finally when the MC saved her, but she literally offers to kill the MC's best friend because she was annoying. Just tons of plot holes. The ending is honestly the worst ending I have ever in my life seen bar none, legit I have read hentai with better endings, it is the worst thing you'll ever read.
