Spoiler for Index NT2:

Brief summary from sections of those japanese parts.

Lots of people at Touma's house. Sounds like a huge party. At first it was only Touma and Index but Touma kept bringing girls home. Confirmed characters at his house:

Touma, Accelerator, Hamazura, Bardway, Index, Catgirl, Kumokawa Seria, Kumokawa Maria (probably Seria's sister, is a classmate of Maika's and gets top grades), Maika, Komoe, Fremea, Awaki, Kazakiri, Sphinx, Fukiyose and Himegami.

Apparently, the members of ITEM went looking for Hamazura which eventually led them to Touma's house. That's where Mugino meets Accelerator and Takitsubo gets jealous because Fremea is sitting on Hamzara's lap. Accelerator sees Tsuchimikado when he goes out to the balcony. (He's on the balcony in his house). They talk briefly about the 'freshman'.
