At page 155, the story "Twinkle Twinkle My Sister" author is NOT [ Taru Kiichi (樽木一) <- not verified ]. (down-vote please)
You can see the Furigana in the same page above the kanji, the name reading is Tarumoto Hajime !!
Edit: also, MSimm1 used the wrong kanji here. The second Kanji is not the one of KI ="tree", but the one of MOTO (HON) which has an additional stroke, see pg. 155 at bottom right again.
