HAPPY Taisakusen:
-A warm song made for the ending of concerts.
Aishuu Romantic:
-Something along the lines of "Suki da na Kimi ga" part 2.
-Sayumi's skills (dancing, singing, etc) have "stabilised" lately.
-Mizuki has a "golden ratio"?.
Watashi no Dekkai Hana:
-He says Haruna's voice is "moe".
-Song contains Ayumi rapping. Her voice has a good rhythm.
-This song was written before Reina's graduation announcement.
Nani wa Tomo Are!:
-He wanted to create something with a feeling similar to "Suki na Senpai". It's a song about growing up(?).
-Erina acts like a kid, bit sometimes she shows an adult side.
-Kanon's smile is the power of 9th gen.
-Haruka's face has chanced. He feels as though she considers 11th gen (Sakura) her rival.
-He briefly mentions something about a future 12th genration.
Daisuki Dakara Zettai ni Yurusanai:
-It's got a similar melody to "Kanashimi Heaven".
-He says Riho's strength is in dancing, but her singing is good too. However, she has a way to go in terms of pitch and vibrato.
-Sakura's still a beginner, so she's got lots of big hurdles to overcome.
Some of these are probably wrong, but hey. It gives people an idea of what Toonk is saying.
