No, there's no more chapters so far. This story is still on going but, currently, Nekota Yonezou is more focused on her other series: Hidoku Shinaide.
The only other part of Elektel Delusion that she drew recently is a doujinshi. If you haven't read it yet, here is the link: http://www.mangago.me/read-manga/shinaide_elektel/uu/shinaide_elektel-chapter-1/27/
Does anyone knows if this manga will release new chapters or are there already new chapters but no one is translating ?? My heart just need more of fumi and shunpei
