Table schema:
CREATE TABLE table_name_26 (episodes__tv VARCHAR, extra__2 VARCHAR, broadcasts__tv__1 VARCHAR, directors VARCHAR)

Question: What is Episodes (TV+extra) 2, when Broadcasts (TV) 1 is less than 13, and when Directors is "Shigehito Takayanagi"?
SQL: SELECT episodes__tv + extra__2 FROM table_name_26 WHERE broadcasts__tv__1 < 13 AND directors = "shigehito takayanagi"
