「あの時、先生が届けてくれた言葉は──」
かつて大也が通っていた学童を訪問するブンブンジャーの面々。
そこで児童たちにギター演奏を披露する大也。
そんな大也を見た職員が、ふと彼の淡い初恋の話を始める。
初恋の相手はまひろ先生。
独りを好んだ大也少年にギターを教えたのも
まひろ先生だったと目を細める職員。
しかし彼女はもうそこにはおらず…。
大也の過去の話に花を咲かせている中、苦魔獣が来襲。
咄嗟に児童を守ろうとした大也と先斗が攻撃を受け、
昏い夢の中へと誘われてしまった。
懸命に起こそうとする玄蕃たちだったが、微動だにしない大也と先斗。
外界と遮断された夢の中。
大也の前に現れたのは、もう会えないはずのまひろ先生だった──。
``The words that the teacher delivered to me at that time were...'' Members of Bunbunja visit the schoolchildren that Daiya used to attend. There, Daiya shows off his guitar performance to the children. An employee who saw Daiya suddenly begins to talk about his insignificant first love. Her first love is Mahiro-sensei. The staff member narrows his eyes and says that it was Mahiro-sensei who taught Daiya, a boy who liked to be alone, how to play the guitar. But she's not there anymore... While the story of Daiya's past is blooming, a beast of pain attacks. Daiya and Ponto immediately tried to protect the child, but were attacked and were lured into a dark dream. Genbo and the others try hard to wake him up, but Daiya and Ponto don't move. Inside a dream, cut off from the outside world. The person who appeared in front of Daiya was Mahiro Sensei, who he was supposed to never see again.
